I don't know if any of you have tried clicking any of the links that appear in my "Adsense" box. As the host I am not permitted to click on them, but I did notice one and copied over the web address.
And I found this:
The company is called Sinus; the firm produces about a million valves per annum, and based on what they say, of very high quality.
The valves appear to be made from Nimonic 80A, Nimonic being one of the Wiggins-developed "super alloys" that were invented for gas turbine blades.
As may be seen in the picture above, the company offers special coatings, for example the gold-coloured titanium nitride; other super hard-wearing coatings such as zirconium nitride are available and in the "ultimate" range, a specially-developed oil-retaining surface finish. Stellite-coated faces are also offered.
On the company's website, apart from details about the products, there is a short film showing some interesting aspects of production - well worth a look.

Have you enquired about Fulvia valves? It seems by the look of the pictures that modern high performance are very flat compaired to the tullip shapes of yesteryear
No, I haven't contacted them: and I wonder what a "small quantity" is for a company that makes a million valve p.a.
On the shapes, well at Evo we always used to back-cut the valves...
