I'm looking for a set of factory replacement stampes metal rockers. Can't find em anywhere but through ford and they want 26 bucks canadian for them each. this is on my f-150 pick up with a 302 in it. Does anyone know where to get a set of these rockers for cheapish? i thought about going with a stud mout swap kit from crane and using a set of roller tip rockers i have but that would require tall valve covers and there is no room for that. plz help me.
