WTF?? Guess what? I DID read the post by Brian. I presented the facts I have: what our bench read. Guess what else wise-***? these heads were bought (from someone other than Brian) with a 2.02 valve, a VJ and a "blend". You should READ my post; I said CLEARLY the vj was very conservative and I'm SURE there is to be flow gained there. There are many versions of a "valve job". My comment about the plug in the chamber was me pointing out that was the only way WE got 273. I guess I should have made it simpler for YOU to understand. No two bences are the same? No ****, Sherlock. Chanages in air density will also effect flow numbers, maybe I should have clarified the weather conditions also.
I didn't start this to bash ANYONE, or question their work. I was stating facts as I saw them today. See, I like to SHARE information. Especially where I know very little. Wish I were you since you know so much...
