I understand that porting work on the intakes and exhausts to smooth them out and "match" them to the manifolds picks up an easy 20HP. Would be even better if coupled with some free flowing headers. Or failing that, just a larger engine pipe, free flowing muffler and tailpipe to provide a less restrictive exhaust system.
