Look at the article again………………It is very clear as to what to use………………….. STEEL GASKET with RTV………..The year vintage of the engine is not important.

The mention of a composite gasket is referring to “if you have crappy surfaces” and until you have it apart and with cleaned surfaces, neither of us knows that………………………….If you are not sure, post pics..
