4agze valve cover gaskets.

To my knowledge they all share the same valve cover gaskets since they are the same design in that department. The only difference is internal. e.g Bluetop and early red top have TVIS and lower comp ratio. Late Red top doesnt have TVIS, is a small port and has a higher comp ratio.  4agze is the same as the red top, difference being forged internals and the appropriate ancillaries.
