Reasons for rings not "Seating"

That's what a clean rag soaked with oil is for, and an oil change after 20 miles, which you'd do anyways.

if everything is cleand like it should be, then you will not need to change the oil at 20 miles
when you change the oil at 20 miles you remove the hi-pressure lube that was used.

I tell my customers, when I build there engine, to change the oil some where between 500-1000 miles, then run dino oil for 3000 more then they can swap to synthetic oil if they so choose too.

you can never get the inside of a block or the bores clean enough.
