[Nitpick] As far as I can tell AMC heads are manufactured in Spain. Aluminum Head Rebuilders is a distributor of AMC heads in Portland OR. [/Nitpick]MarkB.NV said:Search terms would be Clearwater or AMC. The AMC heads are more expensive and located in Washington area, but have established a good reputation.

Huh. I just got my AMC head from AHR a couple of months ago. Strange that they can't get them now.Red Dragon said:Well, here is what I've found out so far. I called Aluminum Head Rebuilders and AMC heads are pretty much unavailable. Chinese heads are what he can get. Clearwater also uses Chinese heads (w/ valves/seats and springs for $325) with a 5yr guarantee.
The person I talked to at Clearwater said that the OEM heads were a bad design corrected with the aftermarket casting. But the person I talked to at Aluminum Head Rebuilders said that the OEM casting was fine and the problem was the how the valve seats were ground. Too close to the edge which caused localized high heat which lead to cracks or burnt valves.
Sheeze, who's right???
