Thin SBM head gasket part numbers?

I have had no personal experience with those Mr Gasket head gaskets, BUT everything I have read about them points to they don't hold up well.

Wolfie boy is a good ebay seller. He sells the hard to find MP thin head gaskets. I've gotten several pairs from him. He's a good guy.
