What kind of port work did you do?

How are you actuating your 6PI?

That manifold that you used has to flow better than the stock 6-port manifold, maybe you can get 200 WHp. I am really convinced that the biggest problem with 6-port blocks is the late intake port close and the second biggest problem is the intake manifold.
