Default 799 heads ptv clearance?!

I'm buying a set of 799 heads, was wondering what the ptv clearance would be close if I milled the heads down .0065 and used a .40 cosmetic gasket with the Torquer v2 cam. Its in an auto car by the way. Let me know what ya guys think!!

That would need to be checked in person, too many variables...

You might be able to get an "idea" on what it may be from someone who ran a similar combo, but you should still check so you don't cause any damage...

Same concept with pushrods, check the length after the engine is assembled then buy the PR..

Good luck

Would I see gains from bumping the comp ratio up to 11.1

You're not going to gain much, if anything, if you just mill them .0065 If you're going to mill them, at least go .030.

up to like .010 is considered a resurface, not a mill for compression increase. .030 (total less then stock) with a V2 should be fine but always double check.

.0065"? That's about 1cc. Hardly worth anything.

Check PtV... see how much room you have and mill upto .030" without much affect on flow.

Best thing is to mock assemble first, check, then mill according to results of PTV.

Milling 0.0065 won't get you 11:1...like other post said go 0.030" if anything and make it worth your while..

I have mine milled .020", I'm running a 228R with plenty of clearance with a stock MLS gasket. Texas Speed told me the Torquer V3 would be cutting it close. Based on that with yours as .006 + the thinner gasket, I think you will clear, but like mentioned you need to check anyways.

What fuel would that limit you to? I'm stuck with 91 octane around here.
