This thin fiber gasket is specifically designed for use with the Titan aluminum Formula Ford 1600 valve cover (Part No. 162-31, not included).
Note: This thin gasket is designed specifically for aftermarket valve covers that have a thick, flat bottom flange. It does not fit the stock stamped steel valve cover or the Ford Racing Ford 1600 Cast Aluminum Valve Cover (Part No. M-6582-16K). The stock cover and the Ford Racing cover both use the original Ford 1600 Kent Cork Valve Cover Gasket, Part No. 164-04.
