Has anyone installed Crower's "Race Only" Camshafts in their LS engine (B18A/B)? Part number CRO-62405. I got a set for next to nothing and am trying to find out what the idle and driveability is like and also what kind of power gains were experienced. I'm not expecting much in the driveablility department, as they are race only, but just would like input from people that have used them. Thanks.

And yes...I know you need Springs and Retainers to install them.
