At 60K miles I find it unlikely that the valve seats or surfaces and damaged...coolant contamination (caused by the gasket failure) could have damaged the guides which can cause all kinds of problems...including damage to the chain and sprockets if it gets bad enough that the valves start jamming closed....so maybe the valves were ok but the guides needed replacement or reaming. The term "Valve Job" can cover a pretty broad spectrum of services. Your chain tensioner might also have been clogged up by the oil/coolant sludge. I'd want to know exactly what was done before drawing any conclusions. If the coolant contamination got bad enough that it damaged the above, it's unlikely that the main bearings, rings....etc...etc we not affected. It might have been better to simply get a used engine.
