. Also have them inspect the top of the pistons for damage when he pulls the head off. If no damage found to pistons then yes it will be ok. Be sure after everything is reinstalled and you put a few miles on it to go back and have him retorgue the heads. The head bolts will stretch some and will need to be retorgued to keep you from having head gasket issues.

I have an exact extra front head off another motor I use fir parts the head is good no leaks . Wud it b ok just to replace front head with the extra good one I have laying around.


I don't see a problem with doing that. Just make sure it is good and clean. No fine grit in it from just sitting around. Might want to change the valve guide seals tho before you install it.
