Triing  to find out some info on some heads I have. My Dad had some heads built years ago through Crane. I believe they are 1968 Hipo 289 heads. They have the built up ridge around the base of the valve springs. They have about as big of a valve in them as you can put in them, and they are bigger domes or cc's than stock. Any possible old timers know anything about Crane building heads back in the late 60's or early 70's? Dennis
