anyone had any experience with supertech valve stem seals? how do these compare to oem stem seals? Would OEM seals outlast these?

 

I have their valve train but I didn’t get to use their seals so I opted for OEM. But my friend just installed his supertech valve seals and no problems so far. I vouch for this company all their products are high quality. I have their Complete valve train that survived two miss shifts to 11k and my motor is fine, and I just ordered their High compression pistons for me and their turbo pistons for my friend. Call 1-408-448-2001 ask for ***** if he is there I think he went down to Florida for an Expo of some sort, very knowledgeable guy.

 

cool. im just wondering if these seals are supposed to be superior to oem in some way or just oem seals painted blue hehe
