a complete replacement would include:
Piston and rings, Cylinder block, Timing chain, Timing Guide, Valves and And lots of oil seals and packings.
rebore would include only piston and rings.
It all depends on the amount of damage. The reason for recommending HMC serive center is warranty. If the work is not done well, there may be overheating or reduction in acceleration. Local mechs may turn the back on you if issue surface again, it's best to get it in Service center.
