i have just bought a 200 sa and the threads are gone n the manifold. i was wondering if anyone would know how to clean these up without talking the manifold off. dont want to fight boroke bolts. would a 1.5 inch pipe tap be the answer??
If the threads are worn/rusted away the hole is allready too big. I would probably weld half a pipe sleeve on top of the manifold and thread into that.
