WICH TFS HEADS DO I HAVE?
i just got a 93 coupe 5.8w with a set of tfs heads on it
i am trying to find more info on exactly wich version i have
i cannot see ant marking on the ends like edelbrock's or afr's
i took the valve cover off and i see tfs-sbf-1 and patent no 6873341 or maybe its 5873341
i would like to know the cc size ,runner size etc...
so i know what i have
any help would be appreciated
