I'll probably set it a little a higher along with using good synthetic oil. Maybe 900-1000 rpm.
Probably use a Mobil 1 filter. My machinist warned me away from Fram's in particular.
I do have roller rockers. They are Harland Sharp's. They have the roller tip, but not needle bearings on the shaft. They just have a bronze bushing on the shaft. They have worked fine so far.
Thanks for the advice,
