Not quite. You do have to rotate the engine to line up the holes in the cam. But those holes feed the rocker shafts on each head. The lifters get oil from the passage that runs up from the oil pump tothe right side galley, which in turn feeds the main bearings, and the left lifter galley .
I took an old pushrod and welded it to the shaft of an old oil pump drive... Not perfect, but free and it works perfectly.
