Anyways Blaine, here is what I used on the junk ass ford motor that I repaired along side the road. Its a kit with 3 different lengths of solid over sized steel threadserts that come with an over size tap. You know the drill, lots of grease on the tap to hold the shavings. Worked like a charm.
P.S. you will be needing another spark plug boot too because the original will be roached.
