Good going guys, I had to replace a cracked head (1/16" gap between int./exh. valve #2 cyl.) on my '74 rallye which I got off a GT at the Rancho Cordova PicknPull. My friend had the metric allen socket for the head bolts. Most of the valves were pulling through the seats anyways. That's the same green as my first Manta back in 1985.
