I'm restoring two post war Continentals at the same time.I've just compleated rebuilding the first V12.I could not find the head torque in any of my manuals,so I torqued it at 45 on the advise of a friend. Could anyone tell me if this is correct. I also heard that you must remove the rear freeze plug before cleaning the block or it would run hot. Well, I can't find a rear freeze plug and the engine is now together and painted.Any help would be appreciated.
