It definitely does. We just made a couple of changes to the chamber and are going to test them to see if it helped or not. The first chamber design we started with has a pretty hefty valve drop. So we made a transition change off the seats that we think should pick up the low lift flow numbers a little. The problem is what you think works, and what actually works are two different things LOL. If the modifications help, I am going to incorporate them into the heads for sale. The combustion chamber definitely does have an impact on the flow curve, but some times it will not show up on the dyno or track. It will most likely take another piece of the puzzle to see any benefit.
