possibly the valve timing if he did not set it properly.

It all depends what he did and how he did it.

Getting the valve timing right is pretty fundamental so I would worry about how other stuff was done. For example, did he use a torque wrench on the head bolts? In the right sequence?

What did he actually do with this "top end rebuild"? What was wrong that caused him to need to do it?

It goes from a simple "set the valve timing" to a "oh bugger, the valves hit the piston and everything is knackered" and all points in between.

So no way of telling from here I'm afraid
