Default l92 vs ported 243`s

i`m building a 370 that will be alot of street and its fair share of abuse on the track, and i`m stuck in a debate on what heads to use. is there a "better" one to use? i know about the inake issue and cam issue. neither bother me as i would be doing a better intake, and will more than likley do a custom cam(probaly through patric g). i`m not trying to make mega power but a streetable 470 would be nice.

Yup, thats what I put on the 370 I have built right now. I am selling it now though. Anyway, was built for boost though but my buddy put down a little over 500rwhp with stock unported L92/L76 setup and fairly conservative cam with a 427 on a mustag dyno. So that got to tell ya something.

A "properly" ported set of 243's are pretty tough to beat....

due to the fact that there is currently not many hi per. l92 intake manifolds
i would say ls6 with ls6 intake, or fast 90/90
