TV, That's a new one on me, please explain.
This is a process invented my metal lock. and we used it to put RR heads back together again when pieces of the cast iron have broken right off.
A hole is drilled and tapped in the center of the crack, tapped, then a screw inserted, this is cut off and another hole drilled ½ way through the last screw and tapped and screwed, and so on along the whole length of the crack.
The Head on my RR stayed water tight and perfect for the 15 years that I was able to drive the car.
