Does the Raylar kit come with all the parts needed for my installation?
In most applications, the Raylar kit or the components on your existing engine contain most all the parts and hardware needed to do a complete installation. Raylar kits are assembled with the additional components that are not being re-used from you original engine. Most of the gaskets on the 496-8.1L engine are designed to be re-used depending on their age and condition. If these components and gaskets are carefully removed and cleaned for proper re-installation the Raylar kit will require that only a tube of GM gasket sealer and possibly coolant is required to complete the installation.
