Yes, I run 5/16" stem chrome plated stainless valves in cast iron guides. No issues. Rick Yamane does also although he may not know it. I did two other heads this way also and there have been no issues. If you run bronze guides you have to oil them. Never oil cast iron guides.

Is anyone here running new EXPOSED stainless valves in cast iron guides, and they had any issues with seizing? My problems stem from the experts fitting bronze guides because stainless and iron don't go together. However, its plain that the iron cylinder head does not expand nearly as much as the guide which then grabs the valve. This is with 3thou clearance. I would be interested to hear anyone else experience. This is a 1935 GTV with exposed valve gear. Thanks for any input. --

Chevrolet big block valves from PEP Las Vegas. Modified to fit the GTV. Durabar cast iron valve guides, self lubricating.

Outside of the laboratory, I don't know how to check to see if the stems are chromed. I depended on the manufacturer to be honest.
