They were made by Ford Motorsport back in the late 80's ... These valve covers if they are to be fitted on anything other then SVO heads will need .025 spacer and 7/16 rocker studs. These covers where made to eliminate stud girdles ... they must have been pretty thick aluminum.
Part # M-6582-A351 this includes the covers, studs, acorn nuts, gaskets, a pilot, and washers.
Good Luck finding them.
