They are to be used with the correctly coresponding timing cover. While the early timing cover was to be used with the thin front seal the later cover to be used with the thicker seal. In the oil pan and replacement T/cover industry there has been issues with mixing the wrong cover with the wrong pan.
In other words if you used a pan that was to be used with the thin seal on the early cover and use a cover that is to have the thicker seal there will be gaps.
Most times when ordering pans and covers they ask what year of block. This determines the gasket to be used and they ship the part/parts based on that detail.
Currently felpro has a gasket for the pre 77 pan/cover with the thin seal and a gasket for the later with the thicker seal
