No, but I can ask my machinist if he has any numbers from previous buildups. Mine are port polished with an angle job-I am getting pretty excited. The engine should be ready Monday

Those are the heads I'm going to be using. My machine shop swears by them in terms of results for cost.

180cc runners? These heads flow to .700, i dont need that much, but even at .500 the numbers are pretty damn good.
Since I can get these heads at a good price, and its going to cost me the same for 180, 200 or 220, I am considering building my 406, which would just be way to much fun but I will have to get prices monday to see. It will be so much cheaper to build a 350, but those extra 56 cubic inches, whoa baby.
Ahh yeah, its just a 305 I swear
