Default Which Head Gaskets?

OK, I called my local Pontiac dealership and they couldn't give me a definitive answer. I bought new LS6 (243 casting) heads for my 99 Trans Am (LS1 engine). My car came stock with the 853 casting heads. Now I need head gaskets for the LS6 heads. Will any LS6 style gasket work? I know this may seem like a noob question but I need to make sure before I order them.

Thanks again
