This is why I went with set screws, the JB was to keep them from vibrating out, coulda used locktite, but when you realy want to fire it up, and your outa locktite, you do what ya gotta do.
isnt there 1 hole in the middle of the rear on the head that isnt treaded? im trying to find out how you guys are plugging this
make sure to clean the buildup out of the holes bc getting them in is much easier than taking them out:Handshake
