Hmm, I wish you had told me that before we removed all those studs. Maybe we could have chosen a more difficult or time consuming method. I was under the car with the mechanic. When he said "go", I quickly removed each stud with a pair of channel locks. They were glowing cherry red. Saw them with my own four eyes. No WD-40 either. I *DO* emphasize, this mechanic is very good with a torch. Knows exactly when to turn stuck fastener. That's why I travelled 400 miles to see him. Don't know how hot aluminum needs to get to warp, but personally would have been afraid to attack head itself with torch.
