Cylinder head exhaust thread repair

My bout with loosening exhaust nuts lead to a damaged cylinder head. The loose exhaust nut rattled around and destroyed the aluminum threads in one of my heads. What a bummer, I had just gotten the heads completely reworked!
Fortunately, Gordon and Rick at MG Cycle told me about Competition Cycles in Butler, WI. For USD $75.00 plus return shipping, they repaired my threads. Essentially, they drilled out my old threads, and welded in a new insert. They cut the threads to precisely match your exhaust nut, so be sure to send them the exact nut you plan to use - do not assume that the stock exhaust nuts are precisely the same as the replacement. I am very happy with the appearance of the repair and have had no trouble with it.
