I was recommended by a friend back in Dec. 2009 about the graphite based exhaust gaskets, Wow what a difference over those cheap FelPro gaskets I had to change every 6 months. For the Buick 350v8 engine, PN: RF13-005 Love things that work! Mac
Major Parts stores like Napa or Kragen don't carry them, I had a local repair / race shop order them for me in Fairfield, CA Also you can check online for distributors, www.remflex.com Cost almost $40.00, ordered a second one for my 225v6 Buick powered Chris Craft boat. Mac
The Napa here in town carries a variety of the Remflex gaskets. I just picked up some for my amc 401 last week. If you have questions about these call the company. They were very helpful when I called.
Glad to hear they're working well for you. I have 2 sets in the shop waiting to be put to use. Bought direct from Remflex.

Oh I forgot those online sources, thanks for the tip. Just gotta remember when you install those remflex gaskets make sure you don't bend them, they will fall apart or delaminate. I accidentally bent one gasket during installation, after that I was more careful, so I straightened it out and continued with success. Mac
