400 Exhaust manifold bolt sizes
Have a 79 Bronco with 400 that has a few stipped out exhaust manifold bolts. Replaced the gasket but burned out pretty quick since some bolts are missing. What size are the bolts? Would it be best to pull the manifold completely off so I can tap the threads? Could I get away with heli-coils? What are some other things I could try?
