Re: Why Mushroom head on Lifter
Several years ago, while overhauling a 312, I discovered valve lifters for a 312 were not available anyplace. I asked the machine shop owner to just order me two sets for a Ford tractor. Lifters for the 134 and 172 industrial engines will always be available. Those little engines were everywhere, think about the M151A1 jeeps. Uncle Sam gave me one to drive, it was the coolest convertible a kid could have. Mag wheels, modern OHV engine, four on the floor, bucket seats, FM radio, folding canvas top, it had everything a kid could want in a convertible in 1967.
