Default Is this normal valvetrain noise?

LSX 427, LME BR7s with BTR .660 springs, adjustable T&D roller rockers and Johnson lifters. I've always been paranoid about valvetrain noises with the LS7 and I have a about a half a turn from zero lash for preload on the lifters. I still think its making excessive noise and am considering giving it another 1/4 turn.

As long as you have adjustability, give it another 1/4 turn and see what happens. If no quieter, go back to before.
