Read your own post Barry Boy. You stated you had heard many times over that heads with good flow figures just did not perform. I am telling you why. No mention of touring car guy. Mind you if he did know his stuff he should have also explained this to you!

You then say your touring car friend says if it looks right then 9 out of ten times it is right. Looks right to who? Someone who has spent hours developing heads on a flow bench or some kid who wants to tune his car?

I'm not saying your touring car friend doesn't know what he is talking about, more that you don't know enough to quote him in context.
