Venom S. In my 514, I recently changed form the .647 solid roller cam to the Comp Cam .585 Hydraulic flat tappet. After 5000 miles I had 6 broken valve springs with the roller. I changed to the CompCam for more reliability and for something that would be easier on the valve springs. I don't really know how they compare for power, but the .585 certainly sounds and feels just as healthy.
