Hey guys.... I'd like to get a few things straight that I keep getting different views on... (First off the engine is a 305 CID from a 1977 Monte Carlo)... what is this that I keep hearing about a non-roller cam, a roller cam, and a semi-roller cam? Which cam's have to be broken in upon initial startup and which ones don't? How much bigger than stock can a cam be before serious engine work is needed to accomodate the larger size? Also, which roller rocker arms can and can't be used on a chevy 305... I know roller tips can, but what about the full roller rocker arm setup? Heads.... how much (or how far) can they be milled to increase compression before it gets to be too far that it will risk hurting the engine?

Thanks in advance for any information at all!! I Appreciate it!
