I was wondering how anyone felt about the new Eldelbrock Buick Heads. I was thinking about using them but the 68cc chamber has scared me off. I would probably have to have them angle milled down to get the cc of chamber that I want. Does anyone have any volume on this head intake and exhaust. Have anyone tried them out yet? Don't you think that because you can use the small block chevy rocker arms makes it more convient.
