Yea, I'm thinking about some L92 heads. The intake ports flow ~330 cfm at 0.600" lift! Damn! I read one test where stock L92 heads and the L76 intake manifold were replaced on a stock or slightly modded LS2 and they picked up 44 rwhp. And those heads are only $399.00 each completely assembled. But I have to wait awhile because I just spent $400 on the dyno tune and I just ordered the JBA cat-back system from Tbyrne. My wife says that patience is a virtue. I say NOT!
