Have you considered using the regular heads, same casting number, and just drilling the different manifold pattern, like Ford did?

I had a machine shop redrill some standard car/truck heads for my 390. The heads I had had the “bosses” so they could be redrilled. They did punch through into water jacket on 2 of the holes. Fortunately, I was able to put some threaded plugs in the hole with a lot pipe dope and plug the holes. Then the exhaust manifold bolts went into the same hole to help plug them. So be careful...,it can be done.

I have a set of C6-AE-R heads, drilled and tapped for 16 (not 14) pattern. Taken off a running motor about two years ago, sitting in my shop ever since.
Also have a set of C8AE-H heads that have likewise been drilled and tapped for 16 bolt pattern. Pretty sure they will need worked.
LMK if interested in either set.
Located in south central Oklahoma.
