From what I had read about these heads, there was nothing "wrong" with them at all. GM and Smokey worked the snot out of them and were unable to show that the gain in HP was going to be worth the additional tooling, engineering and production costs. It seems that there was some kind of plateau they hit like 385hp with the Hemi heads on the 302. Hemi is kind of a 'catch name' for them; they aren't a Hemi head in the traditional sense. It's more of a splayed valve head like a big block chevy than a Hemi head.
