port and polished head

[Lee_P]

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

[mrorange2]

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.

[Lee_P]

so its not worth doing unless you get cams

[mrorange2]

you see more of the difference with cams in.

[FILVTR]

How much will it do (bhp) wise with and without cams?

[nassso]

It's not giving bhp. It's giving better response. That's one of the things you must do if you put cams.

[belly_VTS]

what place can port and polished the head for you?

[Lee_P]

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
