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.

Also good old Ebay sometimes has them too.

Depends how far you want to go with it really?
