i had a valve cover off the mustang the other day to paint it and saw this casting on it, it doesnt look like something a manufacturer would cast on a head so im wondering if my mustang doesnt have e7 heads on it, sorry for the crappy picture, my phone camera is all i have at the moment but it says "CP" it also had a casting number that said "178" on it too.
so are these e7's or something else? thanks for the help!
