Carter also tried a black in color thermoplasic valve.

Reasoning: it was lighter than Monel steel, and not magnetic.

But the sales folks that promised the marketing folks lied about the wear characteristics.

The experiment did not last long.

I still occasionally find one in my NOS stuff.

I still have about 200 of the spring-loaded new old stock original Carter valves to put in the Chevy YF kits.
