Depending on the crank, you might require the H bearings for the chamfer, if there is a large fillet radius on the sides, or you could scrape some material from the outside edges of standard bearings.
Ericnova72 - I've talked to Jenkins at several national events in recent years, he does come off grumpy, lol, but I have seen him smile a few times. Definitely a no nonsense guy,; he's probably forgotten more than many of us will ever know. I followed him in the '60's when his small blocks were taking down the big block MOPARS and Fords. Ahh, the good old days!
