I just rebuilt the topend on cr and put it all back together... but one of the three bolts that holds on the exhaust manifold that hooks it to cylinder is stripped. The other 2 bolts are good. Really don't want to tear it all back down and bring it somewhere to be re-taped. Could I heli-coil it or just throw a little hi-temp gasket sealer around it. Just looking for a little advice maybe i won't have to tear it back down.
