I just put my pacesetter long tubes on with some Mr. Gasket copper header gaskets and they leak bad WTF? I put them on with the convex side out facing the headers and the concaved side of seal against the head. How tight do you have to tighten the bolts before it seals? I don't know whats going on.

 

how did u teighten the header bolts ?
did you go from inside out?
ome ppl use high temp rtv to help seal them

 

Ya, I went from the inside and worked my way out.
I figured if I just keep tighting them they will seal eventually

 

30-35ft lbs would be correct.

 

I can't get a tourqe wrench in there so I am just tighting the hell out of them with a wrench and extension

 

Yeah i got those crappy gaskets to and they did the same thing. So i just put the paper ones that they sent on and i havent hade any problems yet. I will probably put on some fel pro's the next time im in there.

 

It's hard to get 35 ftlbs with a 1/4"drive ratchet or a short end wrench.

 

I've had no problems with mine. How well did you clean the face of the head?

 

HIt up a company called REMFLEXS they make a header gasket the will beat all. They are about 30 bucks. They are 1/8 thick and compress to 1/16 to fill up any defects.

 

LOL My Luck I have these on backorder, Had heard good things about them.

 

what type of stuff to use to clean the head/header surfaces, i have copper gaskets to and i dont wanna deal with this, what should i do

 

I dunno what you guys are talking about...I put copper head gaskets on my LT1 and I've never had a problem with it since.

 

some pple do some ppl have the hardest time getting headers to seal, the REMFLEXS are just a good saloution

 

Alright get this so I took it for a burn then drove it home and let it cool off, then started it back up and the one side that leaked the most doesn't leak anymore but the passenger side still does. I bet that if tighten them down more and heat it up again it will seal. I heard from another post that they need to be heated up and cooled off a couple of times to soften the cooper.
but I am pretty pleased with the rest of my exhaust duel 2 1/2 with an X-pipe and bullets.

 

Just keep tighting them up, its time consoming
