Anybody did that?
What is the gain if any? The bigger valves should give the engine more
power because they flow better.
Any downside on this except the price?
I remember that Chris Cerveli did that on his 968 Turbo engine and it gave him another 40 HP!!!

I have heard of this, although I used to think the 2.7L came in the 944S- I recently found out that the 2.7L was used in one or two years of the regular 944- I think it was Tabor that told me... Anywyay, it is supposed to be a bettter head than the 951. I'm not sure how a P&P and possibly shaved 951 head would compare though...

Let me know if you find out, b/c I've mentioed this a few times as a possibility- I thought it was a more well thing, but evidently not. I also think that one of the people who used to use them was Garrity, and he's not really around anymore top ask...

EDIT: Sorry- I thought you were referring to using the whole 2.7L head- I was under the impression that it was better overall, not just valves...

 

Yep, 1989.
