I'd have sent it to you Andy in a New York minute. Might have cause a little problem though, as compared to a stock bathtub gasket, the ports are .130" taller than a standard port window, raised .080" over stock and lowered .050". It remains stock port width. We were going to use it on a 451 with 906 heads in a Mopar Muscle Magazine/Amsoil Engine Challenge. We switched to a 500"/440 with the 906 heads so the manifold wouldn't fit.
