hello all

Ive been offered a polished and ported and gas flowed 16v cylinder head for £200 its all be reconditioned and had the valves lapped it etc, when I asked to what extent it had been done the guy replyed stage 3 as it was going to be used for a renault race series.

does this sound any good, they are still std sized valves.

nathan.

what sort of money does this sort of work cost (stage 3)
