can anyone tell me where i can order oversized bearings for connecting rods and crank, and where to order headgaskets that match my bore of 82mm. working on a 90 ls if makes any difference. i know that we cant get them at auto zone. i can only order stock and i doubt advance or oreilys would have either. thanks in advance

Seriously. Everyone on here talks about rebuilding there engine but no one has a clue where I need to go to get my bearings. U can’t put the origi nal back in. So either u guys have been lucky n the cranks are perfect comin g out or you have not reaLly built a bottom end of a motor
