Chad Spears and Darin ? had posted up some great numbers (and pics) on another site I used to be on. A lot of guys raved about their work before parting ways.... but both were still producing great work alone as well.
Last I remember anyway :o
Profiler and ProComp heads.

I have an older article in a GM High Tech or Hot rod or CC, cant remember which. Anyway they tested about 10 different cat heads and even tested the Mast mid bore LS3s on a 408 or 468 , I believe. The Pro Comps did very well against some high end competition . If I remember right they actually made the most peak HP of all tested. That was against AFR, Mast, Trick Flow, World, TEA, and others that are escaping me right now. They didn't make the most average HP, but they were close there too. It was the Pro Comp 215cc heads they tested. Dollar for dollar, they won by a land slide. The funny thing about the test was the heads with the smallest runners, the pro comps, made the highest peak HP and the heads with the largest port , the Mast mid bores, made the best TQ of all the heads. I think the Trick Flows made the best average HP, followed closely by the Mast rectangular port. Interesting article. If anyone wants, I will find it and post more accurate info.
