Hemi heads for 318 - 360?

I would simply find a good early Hemi core and rebuild it. In fact...........I did.

I'm in the early stages but, the Desoto tall deck (330, 341, 345) appears to be a bolt in for a 67 up A body manual steering so far, with stock exhaust manifolds. It still will not be cheap, but nothing is like an early Hemi.

RRR what home are you going to find for that 331?
