Using our own CNC Milling machine we helical interpolate a new thread into the exhaust port to accept one of our CNC MACHINED bronze inserts. The new thread is then CNC milled inside to fit the new rose nut exactly. Because of the nature of CNC machining the external and internal threads are machined coincidentaly(both thread starting in the same position with one thread inside the other) giving a very strong insert. These bronze inserts are threaded and locked in and WILL NOT jack out. We have instock the bronze repair inserts to cope with previous repairs but in the last resort we can weld the port to fill in any poor attempts at previous repairs. Also any remedial welding where poor attempts have been made to secure the exhausts nuts will be included. The head will be also cleaned and AQUA BLASTED prior to machining. We are offering this as a guarenteed repair and the pictures are of actual repairs done in our workshop. Please note we also stock valves and guides offer a complete cylinder head repair service including fin repairs and alloy welding all to a very high standard. Or check out us on facebook.
