It leaks pretty bad on my passenger side. I actually talk to him before "tuner" he even said the same thing fix my leak. I think the reason I gave up messing with my header because it's a PITA. What about the ford hearder gasket is it going to work with my bbk headers? I will give it a shot one more time or just take it to a muffler shop. I hate my header!
I used Percy's dead soft gaskets and their locking header bolts. The side that I remembered to tighten the locking screws have never leaked a bit. The other side that I forgot to tighten started leaking a little bit, but with the dead softs, I just tightened them back up in 10 minutes, and then locked them all down and the leak was gone.
I have had great luck with the Ford MLS gaskets in the past as well.
