I'd tell you that head is perfect :lol:
Really thought many disagree with me but myself and a few locals keep going back to a huge head on smaller motors and they just down right fly ! I've now did this 2 times 548 with dart 410's and 468 with dart 355's, a good friend of mine put dart 360's on his 496 all 3 motors really ran good better then anything around here with the same size motor and smaller head.
