Yeah at $3000 it ain't much of a deal. Where is the "free" labor?? Having your cylinders fit to some 107 pistons, getting your heads and intake worked along with proper cam and tune would go a lot farther in my book...

 

I have the Stage 3 103 Kit 27513-08 installed on my '07 RK. Kit came with SE 251 cams. Mild head work was supposed to have been done at the shop doing the built. I'm happy with the performance. It does have more top end noise than stock. Maybe related to the stiffer springs. Haven't pulled the heads yet to check. But has been running this way for 17K miles.
