Aluminum cylinder heads

Agreed.
I already had my rockers so went with the Promaxx heads. Plus I want to try conical springs and the tool steel retainers so after all is said and done, it'll pretty much be a wash on cost. If I really really wanted to be competitive with the trick flows, I would lose 30 to 40 pounds and lay off the pasta.
My Promaxx heads needed very little geometry correction. Seems they fixed it somewhat as did Trickflow. Probably not as well as Trickflow though.
