Does anyone know if the Skunk2 valves with the S2 stamped on the bottom are the new series of valves, or are those the old ones. I have a set and don't know if they will mushroom when I get them in my head and run them with my stage 3 cams. Can anyone help?

 

The new valves are magnetic at the tip because the new style uses a waffer that is magnetic vs. the old style which had a stellite tip.

 

So the valves with the stellite tip will mushroom? And the valves with the magnetic tip will stick to a magnet, is that the way to check?

 

Yep yep. That's what ***** at Supertech advised me. They are a great company to deal with. Top notch service!
