Where I am at now is with the roller being too close to the ex side edge of the valve tip. Mike at B3 said to run (1) race then see if it starts to smudge. Options are relocate the stud hole a bit inward/different rockers that have a shorter section on either side of the fulcrum (which maintains the 1.6), neither of which I wanna do right now (both $$$ & time consuming on the machining) so hopefully the tips stay good when the time comes (This coming April).
