We are working on a 1994 5.0 Mustang GT... Going to be installing some shorty headers, and I'm wondering where the best place to get gaskets would be. Need to order them or buy them ASAP... do I want square opening ones or circular?

Should autozone or lee auto parts or napa have them ? I have been told copper gaskets are good for headers...

any input let me know thanks!

if you have stock heads than square ones also depends on the port of the header I have afr heads and flow tech headers and had to use the oval port ones. for square port the fel-pro 1415 works great I don't like the copper ones the always leaked because I could never tighten them enough without the fear of stripping my aluminum heads for cast iron heads they work better as you can really wrench on them

for now we have stock heads, so what should I go with? Should any auto part store carry them? The headers I ordered come with gaskets, should I use those or opt for better ones?
