Default Inconel Exhaust Valves

Is there any easy way to identify an inconel exhaust valve from an all stainless steel valve?
Thanks.

Use a magnet. It should grab about half way up the stem but not on the valve itself..

Also the weight. They are extremely heavy and only a few out that don't have flat faces.

Someone correct me if I am wrong, but neither valve will be magnetic from the valve to 1/2 way up the stem.

I had a set of stainless valves I just sold on Ebay. When I tested them the heads and 1/2 of the stem were not magnetic on the exhaust and only the tips of the intakes were magnetic.
