bb or sbc? and whats the model number on the studs? dont quote me yet until i know the heads but he is right if its a sbc because they have press in studs and you have to take them to a machine shop. and if i am correct most of the BB heads have screw in studs so you can use those i know i used them on mine.
i guess i never took a picture of them after the machine shop cleaned them for me but that was a test fit with two when i got them and put on two rockers on each one
