I agree with the Truckster But if you KNOW for sure this engine ran fine with no overheating issues I would say go for it. But realize it won't take the abuse a .030 engine would and drive it accordingly. But with only 20k on it and you trust it, why bother with new rings, honeing and bearings? There is at least another 80k left in the engine. The most I would do is a new rear main seal after I checked the bearings. Just run it the way it is and save your money for other truck stuff.
