Just put a set of K-1 rods in it (7.005", center to center,) and you're good to go, with a stock combustion chamber head. My setup is a measured 9:1 compression ratio and works well with a 66mm turbo.
I figured that was what I would be in for. I guess I'll get to ordering.
On the Weisco spec sheet it says I would get about 10.5:1 did you do anything else to lower compression, like a spacer?
