be more like what exhaust does it have now and are you willing to change it?
everyone complains about header gaskets, I've never had an issue I use stock fel pro exhaust manifold gaskets up top, they are alum. on one side and paper on the other. I never had issues and they are cheap to replace if you need to.
Down low I opt for ball end collectors or get a set of summit header buddies for flat flange style headers they use no gasket. I know some say they have issues with those, I never have. Some chop the collectors off the headers and weld pipes directly to them.
I only hate manifolds because they warp or crack, the studs break and area pain to remove or replace in the collectors. So I usually buy headers.
If you have a set that's good and has good studs down low that you can reuse, I'd use em. If not then you can pick up headers for around 120 new. black painted, which never lasts lol.
