I try to use rotators on all my street builds. This uses a shorter valve and speing and works well on a cam with .350" lift or less. I hadd a /050" shim to the spring. When doing this make sure toy check spring installed height pressure, which comes in at around 45/50 lbs. I've used this with the Max 1#, and should work with the 1007B. Street engines din'r see hi revs so the added weight of the rotators doesn't matter and the rotatores extend the life of the seat.
