The Federal Mogul 3/4 groove mains seem to work quite well; they negate the need (if any) to cross-drill the crank.

johnsongrass1, fully groove mains have a severely compromised bearing film from the groove in the bottom half. That's why they don't last as long and why I don't use them unless they are the only thing available for a given engine.
