Since there was a set listed in the for sale section I thought I would start a thread. Ok so I know they are round ports and were made to run a higher lift solid cam all that but my question is, does this head really flow that much better than say a 16/12/62/48 D port? The intake runners are larger but I heard some say that if you increase the port size you slow the air velocity down and it can become counterproductive. Just curious.
They flow better both intake and exhuast. Exhuast was better then intake for the ap. The cams wher'nt solid, but had more duration(230/240), more lobe lift, and used anti-pump up lifters. Stronger/taller vlv springs. Longer/stronger push rods. Polly lock rkr arm nuts. And 1.65 rkrs vs the std 1.52's.
