Well thanks.

The head is verified true. The stripping happened to a FEW bolts holes upon reassembly, not like it stripped while the car overheated. This is a VERY common issue and is why such tools even exist. Thread certing a motor should have not long term affects as long as it is properly done. It is done on race motors and FI builds all the time to take the additional strain from additional load on the fasteners.
