    Port work

    Can I port my eta's head to match an i's manifold myself or is it best left for a machine shop to do?

    You might as well get the i head and get better flow for less work.

      I wonder if there is that much "meat" in it to go that far?

        There isn't enough meat on the eta heads port to enlarge them anywhere near that amount.

                dude you're a moron. If you change the oil it wont polish your bearings and oil passages. n00b

                    what about the old 323 heads. can those get as big as the I ports?

                      You can flair the transition to smooth the flow, but no you can't port that to i spec either.
