Had the too tight rocker issue on my Austin when I put together the new 4 bolt main 350 in it. Cam maker's spec was 1 to 1.5 turns after zero lash. But doing so made the engine idle fine, but all sorts of issues above idle rpm. I backed them off until the rattled, and then went to zero lash. Shut it off and added 1/4 turn preload and it ran perfect.

That's what my bud said. He also suggested those clips to stop the oil. I haven't had luck with those so he said to get the engine running with the valve cover just sitting on it. Lower the idle as low as it will go and keep running to reduce oil. Then pull the cover and start at the front. Loosen to rattle, then tighten to quiet, next, and next, and so on. Then shut it off. Go back and tighten each the 1/4 turn and put the cover on. Repeat for the other side. Sounds like a plan.

I have a spare set of valve covers you can have Mike! Just cut the top out on 3 sides, but leave the exhaust side intact. Then screw them down to a piece of wood to hold the edge, and bend them open to create a splash shield. Then bolt them on your head and start the engine. The oil will hit the shield you made and drain back into the head. I sometimes tack on side shields at each end if an engine oils too profusely and splashes at the ends outside the shield.
Just give me a call and drop by if you want them.
