connecting rod bearing size?

Too much side clearance can allow the oil wedge to dissipate as well. Get the scat I-beams and have the assembly re-balanced and mic out the crank and rod journals. Be sure to mic out each journal in 3 equidistant spots and from the center out to edges but not on the fillet. Generally, light scoring that runs the circumference of the journal won't cause a problem but if the journal is barrel shaped (larger in the middle and smaller toward the edges), that's a bad deal and will need to be reground. Obvious burn marks or metal transfer is bad too.

Like moper said, crush is gone from heat and pressure. A double roller is also cheap insurance and I've used the Summit brand rollers with no ill effects. It's cheaper (or just a few bucks more) to get new rods with the machining prices here in Denver. That will be decision only you can make. Used rods kinda freak me out as they have a finite life measured in cycles and Lord knows how many times these rods have been cycled. Just food for thought.

BTW, how much oil pressure were you running? If crank and rod clearances exceed .002 you really should be running an HV pump.
