We had the old GN-1R heads from the motor that blew up in BPG 06 and after a long talk with Dan while looking at Schmidts new pair of Chapman S2 heads, we decided the GN-1R heads would meet goal of 160+ and went with them. We expect more now we are using the TA heads.
We know we can fall back on the Stage II heads if we need to, there is a set on the shelf ready to go.
Expect more with the T/As? Didnt you aleady go 170+?Damn how much more does that bullit have?
