jimberg....About timing with aluminum heads. Has anyone here with aluminum heads played with timing on a dyno? I've heard people say you can run more with aluminum heads (which is probably true), but does that mean you'll make more power? I'm not trying to say that it is right/wrong to run more timing, but do you really need to since the design of an aluminum head is a lot more efficient than say the E7TE castings? Due to efficiency, I have been told that they need less timing. Of course this is all speculation. I have no proof either way, but I would like to see some dyno runs with a set of aluminum heads with timing at 10, 12, 14, 16, etc...to see what the differences in power are. Does anyone else have thoughts on this?
Back to the original topic....RobertD, I think you would be happy with any of the choices that were mentioned. I was thinking of going with Canfields (54cc chambers), but am now considering the Trick Flow TWs. But whatever you choose, in my opinion, will be better than stock.
