In 1975, I had a friend with a '66 390 Comet, whose dad was the shop foreman for a local short-haul trucking firm that had a fleet of C800's with 391FT engines, so he was "well versed". The Comet popped a head gasket, and his dad showed us how to change the head gasket without pulling the intake, as was the factory procedure. Considering that it was shock tower car, it went pretty well, just took a lot of patience. He also told us about the problems with the oil drainbacks in the heads clogging, and had a factory Ford tool for enlarging the drainbacks in the truck engines. Only time I ever heard of such a tool, but he had one and he was pretty sharp. Flash ahead to 1977, and a gal friend who knew I had my 406 car says hey my girlfriend has a Galaxie she wants to get rid of, smokes and runs real bad. So I go look at it, pretty cherry 500 fastback with perfect interior, 390-4V etc. She starts it, running poorly on about 6 and fogging skeeters. She says can you give me $200 for it? Well, OK. I pull the plugs, fronts are fine, backs oil-fouled. Drip pan goes underneath and pull a valve cover and get black rain- the drainbacks were completely clogged and covers full of oil. Took a lot of digging with a screwdriver to get all the gunk out. A couple oil changes and it was running sweet and clean. Not a perfect return path indeed
