Ok, and then I said I hadn't heard of them and had no idea they even existed.....

So, recommended for Hydraulic rollers..... Think I'd probably one to speak to someone in their tech department and see what the negatives are when running them with a solid roller cam..... So little friction and wear with a roller.....dunno what the negative side effects might be running them on a solid roller but definitely worth checking into.... Could "cam up" for the top end with a solid roller, then let the hydraulics put a little bottom and mid back in maybe???????
