Those old "Come-along" engines put a lot of groceries on my table for a lot of years. I think the oldest one I worked on was a 220 engine in a 1955 Freightliner COE with a no-tilt cab. We put a set of head gaskets on it with over 2 million miles on the truck, and no telling how many rebuilds of the engine. Torquing those 3 heads with 18 1" diameter head bolts (6 to each head) to 600 ft/lbs. was a 4-hour job that involved walking around the cab many times. My 300 Ft/Lb deflecting beam torque wrench with the doubler on it was 5 feet long!
