best IM for an NA motor without vtec..skunk or blox

if your not gonna be hitting high rpm’s in your car you guys think blox is better than skunk 2 because the runners are longer than the skunk 2 runners…what i got from reading was that skunk’s manifold is for higher reving motors…they have shorter runners…correct me if im wrong…i just have a b20 and im not going vtec …so i want to know which one would do the better job…thanks and all replies are appreciated

the blox is your best bet IMO.
