port matching and polishing

[vr6newcomer 1]

hi guys, just had hy vr head port polished, inlet and outlet, gas flowed, also manifolds and throttle body done as well, i was just wondering if anyone cld give me an indication as to what sort of power increase this work would give? cheers.

prob not a huge amount of power mate,maybe say 10 bhp as a rough guess but from what experience iv had with headwork it improves the power delivery and the driveablilty no end

i wouldnt say it would give u to much more, but it will def be smoother, and maybe pull thro the revs better?
