weak block threads...headstud

I'm in the process of changing my head gasket and noticed several of the head studs had a fair amount of crud on them by the thermostat and exhaust manifold and some decent rust on the threads. if I were to pull the threads out of the block would it be possible to put a 14mm stud in said stripped hole? what is the process for going up in size? could I also helicoil it?

Its my daily driver and honestly I would probably just sell the truck before pulling the motor for a few stripped holes.

It has A1 head studs about 2 years old.

I have heli-coiled head bolt threads successfully before, though I'm sure its not recommended.....

Can you pull the studs and run a tap in the hole to clean the threads up, and wire wheel the studs?I know ARP will sell individual studs. Maybe A1 could send you a couple new ones if that was the route you wanted to take. You can also drill and re-tap to 14mm studs. Although itd be ideal to pull the engine and have a machine shop do it to ensure they are straight.

I coat all my studs in moly lube. Seems to help with the corrosion issues. This was with the "425s".

In my opinion helicoils are stronger than threads tapped into the block. Ductile iron is soft, wire coils are not. Now due to the fact you are tapping the hole larger weakins the overall block strength because it takes away material. Negligible IMO on 90% of engines. I have always had luck with helicoil thread repairs and never had a failure. Did a quick Google search and found some reading for you

This is a great option for repairing stripped threads.
