That's what assembly lube is for.
I've always lathered the stuff on everything apart from the bores which are coated in engine oil as are the pistons when I fit them. I more or less dip them in oil prior to fitting them

I'll pre fill the filter, before fitting it.
Then fill the engine with required amount of oil and crank with spark plugs removed until I have oil pressure.

Once I have oil pressure, I put the spark plugs in. I'll then crank it a bit more with the crank sensor removed again until oil pressure is achieved. I'll then pop the crank sensor on and fire it up.

Hasn't failed me yet.
