In the past I've used a puller (made by Vic Wilde of the PWA7C Northwest Group) to remove a head that had been in place at least 30 years. It consisted of a steel bar 310mm long x 33 wide by 7.5mm thick, drilled to take 2 spark plugs adapted to take 8mm threaded bar so the height of the bar could be set by tightening nuts either side, and four bolts fitted through threaded holes that could then be tightened down onto four studs in-line adjacent to the plug holes (missing out the middle one). The ends of the bolts were turned to the stud diameter. This device was capable of pulling with considerable force - the weakest points were the turned ends of the bolts as they pressed on the studs and these had became slightly dished by repeated use.
On another occasion, when I did not have access to this item - carefully tapping in of screwdrivers and other wedged objects did the job, though the gasket suffered and a new one was required.
