BigSqueeze, what is the problem with the valve angles specifically? Do they cause shrouding? Reversion? With all respect, not trying to argue, just honestly trying to learn. As far as HEMI heads for a chevy, they do have them, but I beleive its for 5" bore spacing IHRA mountain motors. I think Sonny sells them. I don't think they sell HEMI heads for the street level guys for the same reason alot of people on this board slag the Predator heads, it's to far from what the factory offered and would get hounded by other brands to no end, which is I guess the same reason no one offers an improved HEMI head for Gen 2's similar to the Gen 3 HEMI'S (personally, I see no problem with the Predators, dodge did the canted valve thing long before chevy or ford with the poly engines).
