Like has been said....just get the engine to normal operating temp. & put it on the transbrake a couple of times. If the rings are not hooked up by the time you put into high gear, on the 1st pass, chances are that they aint gonna hook up.

With my gas motors, I fire it up and let it run at about 2500 for 15-20 minutes. I also set the timing while its at that rpm.

Is there a different proceedure if you are running alcohol?

Being honest ... that all really depends upon the bore finish quality and the rings used.
Do you know the Rpk, Rp and Rv ...?
The rougher the bore = the less temperamental; as long as it is straight and round.

Whatever you do, (in any case), don't allow any excess fuel to wash the bore before the rings get fully seated.

The best way to tell is to look at your header outlet and look for a oily residue. If you wipe your finger and it feels oily,they aren't seated completely. If they have a dry look ,chances are they are seated.

Rings have to seal in BOTH directions; going up & down.

An engine may not burn any oil at all but, still have a ton of blow-by.
