heads and what not
I've got a couple quick questions about the lo3 and cylinderheads. First off, would z28/iroc heads offer any kind of noticable improvement over my stock lo3's? second rocker arms. Are roller rockers that good of an investment? and what is the difference performance wise between 1.5 and 1.6 ratio arms noticable? If anyone has any info or links that i can go to to read about this kind of stuff it would be greatly appreciated. thanks for the help.
