I actually phoned him, and he said the castings are from Procomp, and his stainless valves are made in Argentina. He says the only reason he uses Argentina valves is that there are no stainless valves made in USA, but claims they are good quality.
As for the castings, which is the most important issue, I heard that they "come from" Australia. But who knows whether they are made there? Are they merely being "flipped" through an Australian warehouse? I e mailed Procomp on where these castings are actually made, but no response yet.
As I mentioned before, if these guys are ligit and honest, these heads are a pretty good deal, but reliability is my main hangup. Casting cracks from cheap Chinese stuff is what my concerns are.
These heads by the way are nice raised port head design with the added benefit of extended intake runners to allow standard intake manifolds. I notice that the claimed flow numbers are lower than Indy 440-1 heads. My guess is that these intake runner extensions have something to do with it.
Mrperformanceparts claims to have at least a thousand heads out there with no problems. I asked them for some references to contact with users of their heads, but all they will do is refer me to a youtube video of a racecar which they claim to have their heads on it. This seems suspicious to me, why they cannot supply me with a few satisfied customers. Maybe there are none?



I'm looking forward to everyone else's opinion on these heads


See ya
