No it is a mono head design. And the cylinders are a pretty good lake race ported. The ports are raised quite a bit. The exhayst port is around 29.8mm. Would .25mm really make that big of a difference on the port timing? Anyway. I found my old stock viper gasket, so that will just go back in with the bender gasket. By the way, does anyone know where I can O-rings for the cylinders? I wonder if AutoZone would have rings that bid?
