Very nice effort, but really who wants an 18 tpi insert as all available exhaust lockrings are 14 tpi (except for yours) :? :?:

As you are in Australia how much to have two bronze 14 tpi inserts fitted ?
I take it the heads ports are CNC threaded so those screw in and hope that parting off swarf is removed and replaced with a machined chamfer for the lead in.
What about pictures of the finished installed product thanks ?
