I was surprised. Rock Auto has Sealed Precision bearings for the Cam in Babbit, and 10 and 20 unders for rods and mains and rods.

Im down to finding 20 over pistons or bigger. With the ridge it has i dont think 10 over would clean them up.

Pistons i have a flat tops.

Sadly the head needs a full rebuild. Hardened seats and new guides. The guides are trash and out of the 6 exhaust valves i pulled 4 are pretty burned up and all the seats have definitely seen better days, im guessing due to unleaded fuel use.
