You are saying that the XE275HL isn't too aggressive for a Hyd Flat Tappet? With a good bit of spring pressure? I guess I will switch back to a HFT from a roller and save the $600.
Yes, that's not what I'd call agressive. I'm running a SFT that is 281/255 at .050 and I gross .620 lift with 1.6 rockers. That's about the same as a Comp MM series lobe.
