Questions I would ask:
1. Cast or hypereutectic pistons?
2. Do the head gaskets require retorquing?
3. Silent(link) or roller timing chain?
4. What is the bore oversize?
5. What are the rod and main journals ground to(undersize)?
6. Cast, moly, or? type piston rings?
Personally, I have bought my LAST mass produced rebuilt engine. I have not been happy with any I have bought or sold in years. JMHO
