Engine milling maths

I never ever take any materiel from the intake side of the head unless it’s to get a port volume for some class thing or something.

The big ***** is if you do that, any intake will fit. So what? What about when you put the heads on a different block and now it’s jacked up.

Take it off the face of the intake manifold. Gaskets are cheap. Heads are not.

Those heads will work on any other block.
They're 'corrected' to fit an intake designed around all those other 'stock blocks'... I know you know this. You must just have your mind wrapped around something else.

All those whom agreed with YR need to do their math over again.
You are just widening what you narrowed by milling the heads ...and the intakes and as cast port windows leave plenty of room to massage and align.
