port and polished head

  1. #1
    ok so ive alot about this but i havent got a clue what it does basicly what is the theory behind it and what performance gains are you looking at
  2. #2
    what it does is opens the ports up abit and polishes the tunnels so the air flows easier and quicker good mod for cams give better increase in power.
  3. #3
    so its not worth doing unless you get cams
  4. #4
    you see more of the difference with cams in.
  5. #5
    How much will it do (bhp) wise with and without cams?
  6. #6
    It's not giving bhp. It's giving better response. That's one of the things you must do if you put cams.
  7. #7

  8. #8
    i think there no point doin it unless you get cams I think anyway cus it the cams that will be the major improvement and the head polish just assists it i think
