W2 Heads for Sale (untouched)

The casting number on the heads are 3870810, the rocker stands are casted into the head (I think that's what you were asking) Also I am not sure on the chamber CC, the book that I have on them doesn't give specifics on this casting number, I know the other casting numbers didn't come in that cc. Also I am not sure about the springs and rockers this is how I bought the heads a few years back, I might be able to call the guy I bought them from he might remember them. Or if you know a way to help me out I will gladly get you the information. Also the intake is a Holly Street Dominator.
