never have soaked my header gaskets. Make sure your header flanges are straight and don't have any metal sticking out ,
retighten them a few times after you run them.
If you're still using single exhaust system, it'll have to be 3" dia pipe,
If dual exhaust system, it should b 2" at minmuim, anything less then these sizes and backpressure will blow the gaskets out.
I know you guys have talked before about soaking the headers gasket over night. I wanted to make sure I was using the right gasket. Are you talking about using an actual header gasket (Hedman/Felpro), or is it a stock manifold gasket with the metal. I gotta get this thing inspected, and have already changed the gasket. It just won't kill the leak. From the looks of the old gasket, the 3 and 4 cylinders are leaking at the bottom. I have some new headers, but need to do some other stuff first before putting them on.
: Any and all help would be appreciated.
: PS: Have you noticed the coverage difference between the Felpro and Hedman gaskets? The Hedman is obviously a true 'header' gasket, and the Felpro is an exhaust manifold gasket. I always new there was a difference in material, just never compared the two side by side. Lesson learned.
