Reply to "hyd roller cam with chi 3v heads"

George, many 351-C cams use far different duration etc on the exhausts than the intake, including this Crane. I always thought it due to stock iron heads and their folded-up exhaust ports. If this is true, shouldn't aftermarket heads with so-called 'corrected' exhaust ports be able to use symmetric cam durations for intake & exhausts? Or do you think this is a matter of 'one-size-fits-all' with regard to cam grinders?
