One of these days I am going to learn to keep my big mouth shut. Like vicious stated, 2G heads outflow 1G heads when ported on the extreme side of things. Stock for stock run 1G heads and intake for sure. I am going to do a 2G head this next month and get some flow numbers for you, it will be flowed on a superflow bench which is the most popular bench around and should be close enough for comparison of some of the published numbers already out there for 1G heads.

2G heads by design are pretty decent even with the smaller unmodded ports due to the velocity and path of the ports and like Shane mentioned would probably still handle 500 HP stock. Now I am closing my mouth like I should have done in the first place.
