If your going to run iron Max wedge heads on the street and you want to use pump gas keep the compression ratio under 10.0 to 1 If aluminum heads shoot for under 10.5 to 1 on pump gas I like and use bigger cams on the street than others do, I like 250 to 265 degrees @ .050 with a 106 to 110 lobe seperation angle and as much lift as I can get, roller cams rock 1.6 rocker help a bunch also
