I posted a diagram of the wire's on the coil's and the cylinder's number's that should help you sort out if the wire's are correct.As far as the gasket goes i would go with the felpro one.I think when the engine's were built at the factory someone was wrinkling up the gasket's upon assembly because everyone i have seen that was leaking you could see it wrinkled up before taking it apart to replace the gasket.
