I just got my Pacesetter mid-length headers in yesterday. I opened them up and to my surprise had a set of nice copper gaskets inside. I also have a set of Fel-Pro 1406 header gaskets left over that I was gonna use on my previous T/A. Which gaskets would be a better bet to use?

 

i have never been able to get copper gaskets to seal, and ive never had a felpro leak. nuf said

 

I've been very happy with the Fel-Pro gaskets, they seal perfectly and haven't caused any problems yet.

 

Thanks for the input guys, looks like it'll be the Fel-Pro's.
