I'm gonna swap my cams, after talking to a few people and reading up a bit I figure that most of my boost is going out the exhaust before I get a chance to put it to good use. I want Stage 2 blower cams, but there are two. By looking at my list of mods, which should I go with. The high lift or the low lift? Any clearance issues I should worry about? I have stock mildly ported non-PI heads, no idea about valve relief cuts in my pistons either....although I could check with a spark plug pulled and a piston at TDC....
