It can be well lubed up with petroleum jelly, no need to pack it full, just nice and "greasy".
I also recommend pumping oil into the engine through the oil pressure sending fitting on the block. Use a pump oil can and a bit of tubing to make a temporary seal. This will fill the oil passages and provide oil pressure rapidly. It may take a few loadings of the oil can, but you will know when it is primed as the oil can will be harder o pump. Jim

The Vaseline or transmission assembly lube in the oil pump is a great plan.

I use a home-made lube system primer, as well...

I's pretty simple... engine oil in a clean, dedicated pump-up garden sprayer connected to the oil gauge port. It's pretty easy to pump in a quart or two of oil to FULLY lubricate all pressure-oiled parts before initial startup.

I have used it on some engines that have say for years without being started, as well. (Just deduct the oil pumped in that way from the initial oil fill.)
