Intake on milled heads

I'm not sure .010" is enough to worry about the intake fitting. There is a formula for cutting the intake face of the head when milling the decks. Good shops will make this cut as well so factory dimension intakes will fit.

i'm not an engine machinest but I think for every 0.010 off the surface you cut 0.009 off the intake side so it was probably done
