I look at some of the cam specs for HRT cams that get posted on here and 90 times out of 100 I could find a SFT that would blow away the HRT.
It ain't all that. I was one of the first guys I knew on the HRT band wagon. But years of testing showed me they ain't all that. The BEST way to do what you are saying is a hydraulic roller grind with solid roller lifters.
I no longer spec HRT for anything that is expected to perform. They can use solid rollers or solid flats.
