poly heads
I've got a 66 poly head 318 i'm building. I want to mill the heads what is the formula for figuring how much to take off the intake?

Re: poly heads
-if it is the 66 -.0123 per .010 of head cut
The actual formula is .707+(SIN(45- intake face angle)

Sin?
I remember something about that sort of stuff from school. You need a scale or something to do that, don't you?
