Trick Flow heads

HP has zero to do with rocker selection's all about the springs you'll be running. I like Hughes now for anything that doesn't require a steel rocker but any decent aluminum arm including the Mancini cheapy is fine unless you're needing open pressures of 700 and up (just my own general rule there). The advice to talk to Mike/B3 is spot on.
I'll call Mike on Monday. As of right now, I have 2 sets of rockers since I haven't sent back the Comp Pro Magnums yet and the Harland Sharps just got delivered.... lol
