Dougs headers beating me with a ball bat
I hate to bring you something else to worry about, But i got my dougs on a while ago. I had to move the engine over to get them to fit, but the last headers didn't fit right either.
But i finally got the headers and new exhaust on and it sounded like the drivers side manifold gasket was leaking. Took it off and could't find where it had blown out. Got some of the XX Carbon gaskets that I had used to seal a leak with the previous headers and it was still leaking.
this time I looked and could see (and feel the air) coming out of a gap on the #7 cylinder. It was a gap that wasn't welded between the pipe and flange at 1 o'clock. Took it to the shop and got it with the mig. However I don't feel that i got all of it, I also think I tacked the bolt to the header.
Just something you might want to investigate, or at least be less bummed about if it happens to you too.
But my bolt holes did line up fine.
