Hemi Heads - and Hemi questions
I would suggest, again, contacting Rich at FASTMAN about the conversion heads. If I remember correctly he has built a few motors using them. He steered me away from the thought of the conversion heads. From what I remember as goofy as the Hemis valve train geometry is, the conversion heads are even worse. It has been a while since I spoke to him but I think he mentioned on the conversion heads some of the head bolts are in awkward spots, compromising the valve train.
