Reasons for rings not "Seating"

[Goat Blower]

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.

crosshatch angles are important as the depth and angle,determine how much oil is retained on the walls and the rate of ring rotation.
not enough angle and the rings will rotate too slowly and not disapate heat properly,while leaving too much oil on the wall,allowing the rings to skip over the surface and cause oil consumption.
too steep on the crosshatch will not leave enough oil on the walls and can cause excessive ring rotation that will wear out rings and ring lands prematurely.
most manufactures specify a 22-32 degree angle, uniform in both directions.
can you hone your block at home?sure, but expect results comensurate with your methods.
