Benzmac, I got the head back on. Runs like a watch, but.. the lifters have a little bit of a tap. Ran up the oil pressure prior to starting the engine as advised. Got good oil pressure when running, but still a little noise, nothing horrendous but, not completely quiet. Machine shop says it may take a little time for the air to work it's way out of the lifters. Any thoughts or advice.
