I’m not a fan of running springs that light(953’s) on a BB SR cam.
Also, I like using stuff I’ve had good results with in the past.
Lastly, +.050 locks may cause some interference issues between the retainers and rockers.
My go to spring for street/strip SR cams on those heads is an Isky 9315 @ a nominal 1.900” installed height.
Paired with Comp 741-16 retainers & 611-16 locks.
