what have YOU tried for header gaskets? got my headers on spent the big bucks on copper gaskets thinking i wasnt gonna have to screw with it and they leak, BAD! whats the trick guys!?! whats your setup? tips? thanks alot!
I had the same problem and tried amost everything. One day I stopped at the local performance shop and there was an old guy there who listened to my header leak problem. He knew old mopars and right away knew what I was doing wrong. He said that 3 out of six bolts (oh yeah 2 are studs in water jackets) are really had to get at on drivers side. What the problem was is that I was over tightening the easy to get at bolts and then tightening the hard to get at bolts as tight as I could. That caused uneven gasket seal. He told me to change the gasket and snug up the easy to get at bolts then tighten the hard to reach ones as tight as I can. Then go back to the easy bolts and re snug them a bit. When I fired the engine it was the first time since I owned it that there was no header leak.
