I don't mean to pile on here, but turning the engine over multiple times isn't a good idea either. I'm sure you put a generous supply of assembly lube on the cam lobes before setting the lifters in, right? Turning the engine over wipes the lube away leaving them vulnerable to failure. It is extremely important to have the engine start immediately at the first few turns of the key. This allows the engine to start lubricating the cam from oil flying off of the crankshaft. Cam lobes are not directly oiled by a passage. They get oil drained on them from the lifter valley and from what flies off of the crank. Spinning the engine either by hand or with the starter produces zero oiling to the cam lobes.
Don't get discouraged. I have been in your position and I got through it. :salute:
