WTF is the deal with people just talking about cams in reguards to lift? A .512 lift cam could be "big" or small depending on the duration and lobe seperation lol.... "What kinda cam is it? Oh, its a .512"

Ditch the aluminum r/t heads/copper gaskets and pick up a good ole cast set with cometics (multi layer steel). There are a few good magnum head porters to pick from, with the blower concentrate on good exhaust flow numbers. If you are not going the stand alone route keep the duration in or below the 220i 230e area, lift can be whatever you can get away with depending on valve releif size.
