I'm pretty sure my exhaust valves are a stock 2 piece design and I've really been thinking it may be a good idea to take the heads off and replace the valves for a better one piece design. I've seen some n/a failures from 2 piece designs that obviously are catastrophic. Not cool.

Has anyone here used a 2 piece valve in a boosted application (I don't know if that is standard for being 'stock' or if it is a Magnum engine specific thing) and if so how well have they held up? It sucks to soak up probably 300 bucks in parts to replace the valves but it sure beats chunking a piston and still having to replace all of the valves, haha.
