Strange indeed. This builder has the best reputation in the area. It's hard to imagine that he screwed this up.

I inspected the lifters after 300 miles and everything looked fine, no scoring on the sides.

The valve lash adjusters are 7/6"-20, so 3/4 turn equates to about 0.04". The adjuster ball sits in the lifter cup, and of course the rod ball on the bottom sits in the lifter cup. At 0.04" clearance the push rod will maintain its position (but will rattle like heck).

I'm not sure how to proceed. I'm not far from being able to start the engine to see if the engine will pump up the lifters at high idle speed. It should pump oil better than my 3/8" plug-in drill (which got quite hot after a minute or so). This shouldn't hurt anything if not, as long as I don't run it long. At least if I do this I'll know that the alternative- pulling the manifold again and checking oiling to each lifter bore, is warranted.
