just wondering what manifold fits the 3k head that has a single outlet engine pipe rather than the twin pipe set up? i'm thinking this may be a better set up or is there another head that is worth putting on the 3k??

The twin outlet exhaust manifold flow a bit better than the singles imho. Not really any other heads worth puttingon a 3k. Maybe a 3k big port but they're a bit overrated.

yeah I was told 3k bigports are a waste of time and I noticed a single outlet manifold on a 3k and was interested,thought it may have been a different head always looking for more power!
