I remember doing a valve job on a 63 Fairlane (yes it WAS a 63) with the 221CID engine..The Motors Repair manual warned about how Ford used some sort of super glue on the head gaskets..Well..I got one...We ended up using a small bottle jack perched on the cam galley to break the heads loose...And then....The SCRAPING...It took forever !!!!...I always thought the 63 Fairlane was kinda cool because it was like a minature full size..The grille etc...Fords and their burnt exhaust valves kept me in the black (profit wise) for years....
