Default Is thier a clearance between head and rockers?

Does anybody know the minimum clearance between the head and the rockers on the push rod side? Mine have .045 looks pretty close.

Running L92 heads and Yella-Terra rockers, ratio 1.7:1

Hmm not sure on clearance. I know some have to grind them to clear so in comparison you have more than they do! Sorry this doesn't help in any way.

Being the rockers are shaft mounted I would say you fine. If it was mine I would run it.

+3, looks like it may be a bit tight near the bottom of the stock relief we see existing in the head. Just clear a little more out. I have done the same.

Looks like it will work to me, shaft mounted rockers dont move..if it clears through a 360* revolution, it should be just fine.

Looks OK to me as these are shaft mounted as stated above. Its the baffles you really need to be wary of, especially if you shimmed the rockers at all. Here are two of mine during installation.
