I am trying to put 66 389 rocker arms on my 72 400 heads. I was wondering if this interchange is possible. I thought that all the rocker arms were the same but apparently I was wrong. Is there supposed to be a spacer under the rocker or somthing that I am missing of my 400 heads sot he rocker has somthing to rest on?
