"clevor" valve clearance question.

[seijirou]

Does anyone know offhand about how much additional p\v clearance the 2.05 intake valve in a 351c 2v head is going to need compared to the no valve relief flat top 86' 302 piston. This is will be with a stock foxbody cam and 1.73 rockers
Right now my combo will have stock 351c pistons 0.045 below deck height at TDC. Which is .035 more deck clearance than stock.

I am not concerned with low compression.

I think the stock e7 head has a 1.84" intake valve diameter.. is that right?

I think the stock E7 head has a 1.78" intake valve; the GT40 and 40P heads had the 1.84" valve I believe. You're gonna have to do some mocking up and measuring to know what you have to do to get those big valves to clear.

Ah, thanks for clearing that up.
