A-block head milling

Thackdaddy said

For every .010 removed from the head surface, .012 will need to be trimmed from the intake to keep correct intake manifold alignment.

For every .010 from the head suface you should remove .0095 from the intake side of the head. That way you don't have to touch the intake.

(My question is this: if I have the head milled on both the block and intake surfaces, with the rail surfaces of the block not being milled, will the intake rail gaskets take up the difference? I'm trying to make the heads "plug and play" without modifying the block.)

I typically mill .040 off my heads and have never milled the block ends. As others have said, you should be fine, but it always pays to check before you final bolt it together.
