Thanks for the input. Any specific recommendations for the intake manifold? Also, due to a problem I had with a 5.3 I was reading up on lifters and rockers. I read something about changing to a "roller ball" rocker which would perform better than stock and also cooler. Heard anything about that?

Thanks again.
