I am not saying checking torque is a bad thing, surely it cannot hurt - but if done properly with conventional head gaskets it should not be required.

For curiosity's sake, why not go out there and put a torque wrench on a bolt now, see what you get?

IMO, copper head gaskets are for race vehicles, ones that you remove heads for inspections regularly. Those usually get a coat of spray too, like copper gasket spray.

Once I've done a complete pass on torque, I do one more pass to make sure all are the same/done. On a head, by the time you get to the last bolt, it may have shifted.

And as you stated, it can't hurt. But just to say, I've seen no-retorque head gaskets get up to another 1/4 turn after initial start. (ARP studs)
