History of the ported VW head? Styles that have come and went....

I am amazed at what a set of unwleded Tims heads can do. There have been some fast cars with those over the years.

The bottom ones are his signature series heads. They are what he recommended to me when I told them I wanted to run an 86c or fk-45.
Just to clear something up, now there are angle flows which are cast with angled exhaust ports. These are different than the ones Sarge is talking about right? Who came up with the idea of using the crossworth style port?

As I recall, Joe Vittone sponsored two Japanese guys to come to the States and work for him as cylinder head porters. The first one was Takayuki Oku, who went on to open Race Beat and do rotary engines. The other was of course, Fumio Fukaya. (I remember going to Bakersfield March Meet one year with Greg Aronson and Jim Holmes, and we went to dinner with Vittone, Bently and Fumio, and I sat next to Fumio.... He didn't speak a word of English, but he always would nod and smile a lot)..
Those angle-port heads Fumio did for the A/MC car made about 8hp more, along with going to the Engle VF6 cam. But when they put that engine (82x89) into the car, it went slower.... Heads came off, and back to a more traditional port design.
Don't forget the cast iron combusion chambers heads as well. Both Gene Berg, and Dick Nuss/Bill Duncan ran these way back when. EMS still ran a steel combusion chamber in their more recent Super Street car, using a Pauter casting. They swore by them to retain a valve job for many races.
Don Pauter also worked with an angle-port head, using steel tubes pressed into the exhaust ports as flanged-stubs (similar to T-4). They ran them on their sand dragster back in the mid-seventies.

I had some heads done in the seventies and eighties that were Autocraft stage 1,2,3,4 and those
wicked billet 3 piece heads.....stage 5....the early heads had a D shape and later as they welded them more the
stage three had a real large "D" to the stage 4 having more of a square port....and the Fives were just huge oval shape
then after that was the pro series "910".....I still have a couple sets of those early ones, but we cut them
so much there is no first fin on them.
I have a set of the first street eliminators that are black coated from CB that Kawell did and they are
definatley nice! again we cut them so much the first fin is barely hanging on.
I would like to get a set of Fumio heads just to check out and try ..............
