cam gift

ok it is time heads are done but not on i am new to degreeing a cam. i put it in straight up because that's what i know, i watched some videos and checked a few things. as is the intake lifter sits up about .020 more than exhaust which as i under stand that slightly retarded right? which says i have to degree cam. based on my compression is 8.5-1 ish. i have read here at A bodies it should be advanced 6-8 degrees to help low end, any inputs on this would help
