Title: Head porters Post by: hotrodsurplus on September 11, 2015, 19:54:27 pm I looked but couldn't find any recent information but direct me to a post if it answers my question.
Who are the better names in the head game right now? Looking for a pretty straightforward job--just a mild port reshape on a 40x35 for a heavy, high-gear car. Nothing super trick but quality and turnaround time are essential. thanks, chris Title: Re: Head porters Post by: Joel Mohr on September 11, 2015, 20:07:00 pm Clyde Berg! 714 231 9555....Does ALL of my head work. including my Pro Gas heads..
Title: Re: Head porters Post by: Martin S. on September 11, 2015, 21:02:48 pm Just dug out some heads that I sent to the Bergs back in the 90s - stock valved semi hemi'd and ported. anybody recognize the signature on these heads?

Mick Wooten! The Steve & Greg Tims at Performance Workshop do very good work. I haven't found anyone who delivers on time though!

Talked to Steve a little while earlier today. I like his ideas and unless someone gives me earth-shattering information I'll probably go with him.

I just left a message for him. Title: Re: Head porters Post by: Jimbo01 on September 13, 2015, 03:14:44 am I cannot recommend anyone more strongly than Steve and Greg Tims. Top notch work and they stand behind their work.

Did they sign the heads?
Title: Re: Head porters Post by: Martin S. on September 14, 2015, 23:46:53 pm Why did they leave the step in the chambers? Was that something you wanted because if you want cc's it's better to do more chamber work and/or dish the piston. Keeping the squish is the idea ;)
Title: Re: Head porters Post by: Zach Gomulka on September 15, 2015, 01:44:07 am The step in the chambers can be useful if you run your cylinders to zero deck. Many argue that it's better to keep the combustion in the aluminium head than the iron cylinder.
Title: Re: Head porters Post by: pupjoint on September 15, 2015, 01:51:03 am Beautiful! Did they sign the heads? unfortunately no.Title: Re: Head porters Post by: pupjoint on September 15, 2015, 01:52:12 am Why did they leave the step in the chambers? Was that something you wanted because if you want cc's it's better to do more chamber work and/or dish the piston. Keeping the squish is the idea ;) i think zach answered above. :) yea went thru this a few times in the end i just left the decision with Greg. Title: Re: Head porters Post by: Martin S. on September 15, 2015, 02:20:38 am I see. Hadn't heard that one before. You are stuck with the deck unless you flycut it again instead of adjusting shims. It's best to not have any combustion in the squish band at all. At least you could flycut it out later.
Title: Re: Head porters Post by: Martin S. on September 15, 2015, 02:29:24 am Mick Wooten even stamped the cc of the chambers in the head, nice touch!
Title: Re: Head porters Post by: ST DRAGN on September 15, 2015, 17:14:07 pm Tims has my vote.. ;)
Are Micks heads welded at the intakes? ( photos ) Title: Re: Head porters Post by: Martin S. on September 15, 2015, 20:43:09 pm No welding, my heads were ported up the manifolds for Kads. At the time (90s) I coulda woulda shoulda bought a set of IDA's from California but used my second-hand Kads instead ::)
Title: Re: Head porters Post by: Donny B. on September 15, 2015, 21:23:42 pm My heads are from the Bergs (GB865) many years ago they were welded and ported by Mick Wooten. He stamped his name and the ccs of the combustion chambers. I'm still running them today after a few refreshes.
Title: Re: Head porters Post by: Martin S. on September 15, 2015, 23:58:51 pm Nice! Are yours semi-hemi'd? That's the only thing I don't like about my Berg heads. Beautifully done semi chamber tho.

Try a flame port too next time. Like this: (my wife's bug 9.4:1 1776)
Title: Re: Head porters Post by: modnrod on September 16, 2015, 01:47:53 am ............my Berg heads. Beautifully done semi chamber tho. How many miles on those heads when the pic was taken? They seem to have an even burn pattern. Title: Re: Head porters Post by: Martin S. on September 16, 2015, 02:35:34 am I'll check my book and let you know. I'm curious too. That engine was sweet - a complete Berg 1776 kit engine with all the niceties. It was a shame I took it apart to build my 2332 since the only thing we used was the case. Steve remarked how good a build it was when dismantling it. I was thinking of rebuilding it as it was then with another case.
Title: Re: Head porters Post by: Martin S. on September 16, 2015, 03:06:26 am OK I have the history on those heads. Started out non-ported from the Berg engine kit ordered from their catalog, but shortly after I sent them back and had them ported and in June 1997 (about $800 USD at the time I think) they were installed into the 1776. Went on for 23,177 km (14,400 miles) with the Kads and then I bought the AJSims turbo kit in August 2004. Drove it with the Weber 2 barrel progressive for 1,206 km (750 miles) and then sprung for an Electromotive EFI setup installed by Steve S. in August 2005 and he eventually turned up the boost to 15psi with the low compression heads (as installed in 1997 at 7:1 CR). Drove that wonderfully snappy turbo for 8,245 km (5,123 miles) before having Steve talk me into 'installing a new cam' and ending up with, what he called a race engine tuned for the street, my current 2332 using just the case from the Berg motor. Total 32,628 km (20,274 miles) on the heads. I have all the parts for the 1776 still in a box and just last week snapped some pics of them to refresh my memory. Thanks for getting me to relive that motor's history! Sure has been a fun ride!
Title: Re: Head porters Post by: modnrod on September 16, 2015, 11:36:26 am Cool, thanks Martin.
I might try something similar on a set, see what the differences are. Title: Re: Head porters Post by: viNce on September 16, 2015, 14:42:26 pm Chong WOO heads ;) ;D
Title: Re: Head porters Post by: Donny B. on September 16, 2015, 15:13:54 pm My heads are semi-hemi and as much as folks complain about that I have had no issues until it ingested a screw that made a mess. My engine went from a 2007 to a 2165 running my trusty 44DCNFs. Now running just over 8 to 1 CR.
Title: Re: Head porters Post by: Fiatdude on September 16, 2015, 15:15:14 pm Nice squish bands. Try a flame port too next time. Like this: (my wife's bug 9.4:1 1776) Don't need the flame port with these pistons (http://i586.photobucket.com/albums/ss306/Fiatdude/pistonsa.jpg) (http://s586.photobucket.com/user/Fiatdude/media/pistonsa.jpg.html) Title: Re: Head porters Post by: Martin S. on September 16, 2015, 15:53:26 pm You could try one on the non plug squish band side in the head. It would match up with that squish area on the piston. If it doesn't help, weld it up. Also you could try dual plugs! :D
Title: Re: Head porters Post by: RhoadsVW on September 16, 2015, 21:34:05 pm My heads are semi-hemi and as much as folks complain about that I have had no issues until it ingested a screw that made a mess. The heads on the green car are semi-hemi from Roger Crawford and I was very satisfied with performance on a 1996cc for over 30 years Title: Re: Head porters Post by: Martin S. on September 16, 2015, 22:50:17 pm Chong WOO heads ;) ;D I don't see your image, it says image expired?

The heads on the green car are semi-hemi from Roger Crawford and I was very satisfied with performance on a 1996cc for over 30 years Try pushing 15psi of boost thru those semi-hemi heads and you will be even more satisfied! Got a pic of the green car? Title: Re: Head porters Post by: Garrick Clark on September 19, 2015, 14:07:02 pm Hi guys. Could someone please explain to me about these flame ports on the squish pad. I'm thinking of adding some to my heads while the motor is still apart. Looking at my chambers there is a lot of squish pad area that has no carbon attached. So was wondering if these fire ports would help.
So to me the burn isn't over the full circumference of the piston top/chamber. Thanks G.c Title: Re: Head porters Post by: Martin S. on September 19, 2015, 23:20:19 pm It's supposed to add turbulence to the combustion chamber and help 'burn it all'. I like how he says, 'shift into high gear at 20 kmh' and that's what I've noticed with the 1776 engine shown in the pic. It is so much fun to drive without worrying what gear you're in. http://rexresearch.com/singh/singh.htm ;D

Very good work. Lots of hours been put into those.
Title: Re: Head porters Post by: Martin S. on September 20, 2015, 22:28:41 pm I was told that you need experience with a flow bench to be able to port effectively. That said, yours look great to my untrained eye. You have the desired cobra shape in the exhaust. My 044 exhaust ports were almost perfect oob but the intakes were 'awful and they could have saved a couple pounds of aluminum by doing it right in the first place'. :o
