Like i said stef there aint meny about,it looks more like a rebuild but dont worry there strong donkeys.Read this about the old valves and how to dispose of them. Important
Worn sodium-filled exhaust valves cannot simply be scrapped. They must be cut in two with a metal saw between centre of stem and valve disc. They must not come into contact with water when this is done. Then throw the valves into a bucket of water (not more than ten at a time). Then step back because a chemical reaction occurs when the sodium filling burns. Following such treatment, the parts can then be handled as normal scrap.
