Exhaust Port Repair

So I have a stripped exhaust port and wondering who' s doing repairs these days without removing all the valve gear. Problem is there was an insert welded in before.

Well, I would HIGHLY RECOMMEND "comnoz" on the forum here (Jim comstock) He did an 850 head for me a couple months ago ... beautiful work ! He has my business for ALL my future exhaust port thread repairs, period. Cheers.
