So I'm installing some Crane Cobra 1.7 Roller Rockers on my AFR165 heads, The OEM 93-95 Cobra ones. In the intrest of getting a smaller sweep across the valve tip, I'm shimming them up 0.090 and using 6.4 inch pushrods. that's two thick shims and one thin from the Crane shim kit under all the pedestals. It's kind of a compromise as to get actual proper mid-life geometry I'd have to put even more shims under to the point where the pedestal would be barely in the channel and there would be not enough bolt on the hole. Question is, think that much shim is advisable?
so with 0.090 of shims I have 0.440 bolt thread in the hole.
with that I get 20lbs of torque at 1/2 or 3/4 turn on every bolt
