What are most people using for header gaskets? I have the copperseals on there now, and the other day I had my header off and I could see exhaust marks where they were leaking at the center two cylinders.

 

Percy aluminum, no leaks. Header flange and collectors.

 

Felpro.

I have the Percy's at the collector, I didnt know they made them for the flange. Where did you get them?, Summit or Jeg's, or an auto parts store?

 

I have percy's aluminum header gaskets and collector gaskets. The header gaskets are awesome as long as you put them in right. (don't ask). The collector gaskets are basically just 1/8" aluminum plates that are cut out in the shape of a collector. All in all, they are great. Summit or jegs has them.

 

I picked up a set of the Percy's collector gaskets at AutoZone. They also had the header gaskets there. I believe most autopart stores are starting to carry them now.

 

i have alum cop 4 dif plates forgot the man but no leaks.was gonna use it as a crutch but theyre real good. had felpros on and blew em in 2 weeks

 

Ordering my dead soft aluminum gaskets this week. Total comes to a little over $50. But for 0 exhaust leaks, it will be worth it to me.
