Ah, heatshield bolts. I used penetrating oil and was super careful to ease the first one gently, and it still just snapped right off.
Unexpectedly the rest came out okay. The biggest pain is the ones which hold the two halves of the heatshield together, as the shield just wants to bend. I ended up just cutting around that. The chunk I cut off pinged away and I couldn't find where it went.
Later, when I pulled off the M25 in a cloud of steam, I worked out it had landed in the radiator fan shroud and eventually got hit by the fan, flew up and punctured my new radiator. So that was nice.
Anyway, try not to do that, is my advice.
