    Worked this problem a number of times. Corrosion between the steel bolt shafts and the aluminum head is locking the head in place. Wedge between the head and block will usually damage both. Best bet is to clamp the head only in a large vise and using a 1/4" drift/punch hammer on the ends of the broken bolts/studs. Work around the head tapping/beating on all the broken bolts equally. The force and vibration will work it free.
