Engine milling maths

No it is not complicated unless you make it. .120 off, standard tolerance? Not in a million years.

Do the math. I took .040 off the head. The width of the intake from high to low is at least .060 so that’s .100 right there.

I have no idea if some dick took .020 off the head before my customer for them. Who knows, maybe they already took .040 off for some reason.

Real life isn’t like the comic books.

Do what you want, but it will bite you in the *** someday doing it that way.
