I have done some searching, but came up with some mixed results. I'm looking for replacement valve seals for my setup.

Patriot Gold Extreme Dual Springs .660

 

I believe I answered my own question. "The all new PRC .650" spring kit is the newly updated replacement to the old "gold, Platinum or xtreme" valve spring that has been around for years & years." I'll just buy a set of seals for that then. Useful information for anyone searching in the future anyways.

 

just buy the stock valve seals from GM.....
cost effective and they work great...

there are 2 types... I cant remember which one is which... but one version has the seat and one doesnt...you want the version without the seat.
