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

Try pushing 15psi of boost thru those semi-hemi heads and you will be even more satisfied!
Got a pic of the green car?

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

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

Did these myself, comments?

Your chamber shape is like mine except your plug is closer to the valves . Very good work. Lots of hours been put into those.

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'.

Put a smiley in my last post because there's sort of a myth between this name we don't know who's the real guy behind this pseudo, maybe Shawn Geers or one of his team.

Excellent! I like the photos, in focus with the proper lighting. Note the finish of the ports still has the swirl marks. The pros will push the guides out of the way and then back into position.

I have met him, he is very real and very skilful, but has no desire for the fame and name in lights treatment, He has done some work for me before and I have some 94mm bore 910 heads he has done for me for a new engine I hope to finish this winter
