I used 10* Super Locks designed for lash caps on my first pair of heads with SA rockers and they provided additional clearance for the SA rocker arm rails. I put about 4,000 miles on them with no problems. I did not use the lash caps, just the locks.

I replaced those heads recently and used regular 10* locks and Manley SS valves with .290" tips. That is the proper way to do it. The .290" tips provide .035" clearance between the locks and the SA rocker arm rails.
