It's clear the Gen 2 heads were adapted to the wedge block back in the day, it's definitely not a clean sheet of paper design.

Are these iron heads?

I feel the angle should be checked and corrected, but without a print I don't know what it should be.

These deals lead right into becoming a classic Mopar parts hoarder just to have extra junk to mock up
with, and observe (if the same problem exists with 2 or 3 sets of heads, and they all have the same angle....
then we can assume it's probably not the heads).

But......with three intakes/one set of heads showing the same issue, it seems we've headed down that road far enough already with intakes instead.

If they're angle milled, then I would think there would probably be some major changes made for pushrod clearance. How does that look?
