Because those are hydraulic flat tappet like numbers.
Unless they are very quick ramps , it is gross overkill to see moderate lift and duration numbers like this in a roller.
Is it a hydraulic roller ?
That would make more sense.
I am not slamming the grind at all......but I tend to think that mild solid rollers start around .400 lobe lift and 240ish @ .050 and get pretty extreme from there.
