Gasket for installation of exhaust headers on "raised port" 2.2L and 2.4L CIH Opel cylinder heads. Made of upgraded high-temperature "crush fit" material, this style also accommodates the separation of exhaust ports from #2 and #3 cylinders, as well as an intake manifold. (Notes: Also see our adapters part #6338 and #11033 if installing a 1.9L intake manifold modified for fitment to a 2.2 or 2.4L cylinder head).
