Off-season engine freshen

New rings, bearings, head gaskets and other gaskets. New valve springs, rebuild lifters or replace (depending on run count). New belt, crank seal, and cam seal (belt drive). ATI damper sent to ATI to be rebuilt. (I no longer run the ATI damper but when I did, I had it rebuilt with every overhaul)

Rods and crank get magnafluxed. Check the runout on the crank to make sure it’s not bent. New rod bolts with the big end checked (as stated by others above). Pistons get skirts re-coated.

As for machining, align hone, torque plate hone, and valve job (if necessary).
