the thitek heads flowed exactly what Craig Thibeau said they would on my bench. In a phone conversation with "someone I would rather not name names" said the BES Apache heads go 400cfm at .600 which would be better than the Thitek did on my bench and better than Thitek claims. When I said my Apaches flow 360 @ .600, his comment was that is what they flow stock. I changed the subject then.

on another note, I see companies offering Apache heads ported by Thibeau at Thitek and never see any posted flow numbers on them.
