Maybe just stay with stock pistons and add street port head work, .030 head gaskets and cams. Nice improvement for minimal $$

 

On my 2010 Limited, I'm running:
Jackpot ceramic coated headrers
Woods Cams and Pushrods from Fuel moto
SE High Flow air
Thundermax ECM
Klock Werks Slips

Runs like a bat out of hell. 6th gear is a whole new world, it is like being in fourth.

 

I have the screaming eagle stave IV kit right from the catalog with a Dragula 2-1 using a SERT tuner making 119hp/117ftlb love the power

 

Chris Rivas 574ce cam should produce 95-100 hp ,100-115 tq with a nicepipe a/c and proper tune. This is the info I received from the tech at rivas's shop today. That's pretty good I think for a bolt in cam.
