Moly rings... run it hard after a couple heat cycles.
Unless it was machined by Fred Flinstone and comparable time frame equipment, run it hard.
What do you think happens to an engine that is put on a dyno for first fire up. Last one I did had a few minutes to warm up to operating temp and check for leaks. It then got treated to about 30-40 pulls from 3500-4000 to 5500+ rpm.
