I was poking around under the deck of a late block and wishing for some material to appear right there, that would have solved my block availability problem.
I think there's enough metal in the iron heads to relocate those holes by stepped sleeves. Aluminum 21 stud heads could maybe be ordered without those holes drilled. I wonder why Ford added studs instead of just relocating them, anyone here have sealing problems with 21 stud heads in that area?
We have a local guy here who makes new alloy 34 stlye heads with pump in head.

He has them cast and does all the machining himself.

I am sure he could change them a bit if needed.
