Feeling a bit chuffed having got all the studs out of my block without mishap preparatory it going into Park Engineering for new valve seats.
Not having removed studs for forty- five years I invested in a couple of Koken extractors (1/4 and 5/16). These give a very good feel for what the stud is doing and an "oh sh##" moment when I thought I'd snapped one proved to be the Koken's idiot proof feature that appears to cause the extractor to let go above a certain torque. Still needed to get the Stillsons out for the long one under the water inlet which had corroded so much it was in between the 1/4 and 5/16 sizes. Heating and hitting the reluctant ones did the trick.
