Quoted From dreamer2355:
I would first do a cooling system pressure test as well as a block test to verify you do indeed have a head gasket issue before attempting to do all that work.
And i agree with college man, you will need a good FSM manual with all the procedures as well as torque specifications and all the correct tools.
Good luck and keep us updated.
+1 big time. Make SURE you need a head gasket before you do the job. I’ve seen inside the hoods on those cars. I don’t envy you getting to the exhaust manifold on the back side if you end up needing head gaskets.
