This is the kind of gasket that's cheap insurance to keep on hand if you're doing any top end work on an iron-head 6T, since rocker box gaskets tend to get torn or hardened every time the box comes off.
Our catalog record ties this specifically to the iron-head 6T era of 1960-1962. If your engine has an alloy head, this isn't your gasket, so check what you're working with before ordering.
