so I am running the old Harland Sharp roller rockers with the .625" shafts, shorter than the newer units. these rockers are from around 1975. they are better in a way than the newer ones because they have more needle bearings-no spacers in between the needles. running a .550" lift flat solid cam for 35 years. hey B3, what U think? I have not measured anything. stock heads, 11/32" valves, about stock length, (small chevy +.100") . runs good to 7000
