I'll second this and I have the paperwork to prove it if there's any doubt. The Pro Maxx casting is as good as any American casting as far as quality of material and workmanship. Definitely not the norm.

They are machined in MI by Uni-Bore. Scott has paperwork here that is documentation from the Chinese mfg. It was left in the box on a set of BBC RHS heads. I also have contacts at Comp and they have confirmed all of the stuff is Chinese origin. It has been for many years.

Why is it we never have time or money to do it the right way in the beginning but we always have time and money to do it over again?

Ok, Thanks for clearing that up. Glad my friend went with afr instead especially after this information.

After my personal experiences with both heads, I'd go with the ProMaxx. The castings from both heads are fine. Both very good quality castings. I personally don't like the port design on the RHS heads but for me, the problem was in the machining. The RHS heads were so bad that I had to return them. Fixing them would have meant pulling all the seats out and replacing them. Getting a new set was a real PITA and then, the new set they sent weren't all that much better. So far we haven't had those sorts of issues with the Pro Maxx stuff. Ports and chambers in the Pro Maxx stuff are good design and perform well.

Like Chris said, I have a bill of lading that was in the box with the heads that RHS replaced for me. They came direct from Royal Oak Boring in MI, and the bill clearly says "BB Chevy China Casting."

Are you able to match the AFR 265 heads for less? I know those run around $2,300

If you asking does ProMaxx have an oval port no. On cost on the Promaxx, the board doesn't like prices quoted. You can email me and i will send you a quote.

Re: $2600.00 to spend

650 Hp from a 540 with a roller cam? Find a set of used "GM" Edelbrocks. I definitely wouldnt use any local machine shops - let those guys starve (you need a master BBC guru to assist for this). When you you need a crank polished or a set of rods resized 5 years from now and its cheaper to buy a new set than to have them shipped across the county and back, make sure you buy them from whomever the current internet master is.
