right a little disscusion on port polished heads.

the question is, do they really work???

now im not talking about cams, or big valves here, i mean just opening the ports up.

i have spoken to a few people, one of which used to be a touring car machanic, and i have been told, that opening the ports on a turbo head is a waiste of time, as your forcing air in and out with your turbo.

and when i had my head overhauled, the guy doing it was going to have a look to see if there was anything restricting the flow, which theres not on a CVH head.

So is spending all this money on getting your ports machined and polished a waiste of time???
