Theres better if you have to stay with conv. heads. go with spread ports if allowed
I think them are the new dart 360's, the dart 380's arent anything special. My motor guy put them on his 582 identical to my 582 and it was a higher hp then mine with BMF 385's. The dart 355 is a very good head for a 540 CI motor. As far as the sniper intakes they are decent out of box compaired to a super victor, but both do have some room to be had with a little work.
