Perfacar "hi, usually rule is , .060 min clearance retainer to seal. .500 lift is about max.
at RPM, things hit each other. just food for thought."
He beat me to it. The loss is somewhere around .020 or so, maybe a little less because it's not a hydraulic roller. IMO I'd limit lift to .500 advertised because it's still a little too close for my comfort. I like at least .060 as Perf mentions, especailly given the capabilities of the cam.
