ok i have a set of pi heads that just came back from the shop they are fully assembled and the cam sprockets are off of them, im wondering how do i tell which head/cam goes on which side???? are the cams the same and it dont matter?? im thinking these are romeo heads because of the removable cam sprockets and the ladder type tower on the top and i only count 9 bolt holes in the top of the head for the valve covers (which 2 more in the front that go in the timing cover would make them 11 bolt right?) but ya how can i tell which one goes to which side
