I should have explained better. Chrome is oem and will last the longestn however its harder to get to seal. Like if you plan to have your block sent out and properly bored and/or honed, then sure. However I rebuild my motor still in the truck with the crank still in. I honed it with a harbor freight hone and $15 drill. I have perfect compression and oil pressure. So depends on your needs.

Plus regarding lifespan, I still think the moly rings will outlast a head gasket, so if the headgasket goes, your already 3/4 the way in for a re-ring.
