    I'd give Form-A-Thread a try before going the new manifold route. You may also be able to tap it out to the next size, and ream the water neck.

    I had the same problem on an 87 caprice with a 305. It never sealed right when i tried to fix it. It just kept leaking. You might be able to drill it out and tap a bigger hole. I started looking for another manifold until a lifter grenaded and took care of my problem.

    Well you can get a tap and die set and drill out the holes and tap new threads for the next size bigger bolt. Or you can get a heli coil with the same size threads as stock from a auto parts store. but You will still need to drill it out and tap new threads to install the heli coil. If you dont want to do any of the above. Pull the manifold and take it to a machine shop they will be able to fix it for around 20-40 dollars

    You can get heli-coils at almost any parts store. Once you have these in, you won't ever have to worry about the holes stripping out again.
