Does anyone know if the bolt pattern on the cobra 4.6 exhaust manifold gaskets are the same or close to the ones on a 3.8. I just installed a set of mustang tubular headers on my SC and the drivers side ( the side that had to be dented a bit to clear the steering shaft) keeps blowing the gaskets in 2-3 dsays. Not only is this loud and annoying but its a real PITA!!! I was wondering if a set of the PERCY'S deadsoft blow proof aluminum header gaskets for a cobra would work?
