I have a set of 4X-1H date code D294 both heads. Rockers and valve springs have been removed but I have stock ones to throw in if you want them. Valves, guideplates and screwin bottleneck studs are still in them.
Off a 74 455 Trans Am I destroyed as a youth. Virgin heads with about 75k miles on them.
I am just down the coast in Oceano and have other parts if interested.
