Break-in new lifters

This is going so slow. Found the last factory right bank piston left for a 70 340, finally found rings, they came .060 over; standard set coming next week.
So, found the lifters leak down after weeks of sitting, even ones under no pressure. bought a set of sealed power; half wouldn't pump up in a can of oil. Swapped them for a new box-1'st 2 pumped up, set them aside.

Now, the problem-upon fire-up, I will have one new set of rings on a new piston, new lifters on an old cam, and a new-to-me empty 727 trans (lines and radiator cooler empty, too). Too much to take care of at the same time.

Do I really need to 2000 rpm upon start-up? Lucas pre-lube
