it recomends roller rockers
but all the lunati spring for a sb are doubles with a damper and need machine work/pc seal to drop on
but...comp 901-16 cover all the sb cams they have
all the sb cams use the same lunati spring part #
and the comp 901 is within 10lbs of the spring rate and are cheaper,drop on with stock seals and no machine work
I did mine on the engine when I went to roller cam 60710
does look like a good one though
IMHO the 292/292 would be better and have a much better sound at idle
the 60710 is smooth like a stock cam
