I say skip the GM OEM ones altogether and get the Percy's Seal-4-Good gaskets. They're aluminum instead of steel and will provide a better seal than GM OEM gaskets will with headers. They "compress" more when the header pushes against them, offering a much better seal than any other gasket. They're very thick. I believe there are 6 layers of aluminum - they're very cool looking. I used them with my headers. Headers just went on and no leaks at all 
You can get the Percy's gaskets from Speed Inc. also. They're a few dollars more than the GM ones, but they're a much better performer and IMO, $15 is worth the peace of mind.
