Thor's resistance to pain and ability to survive extreme injuries has always been incredible for someone without a legit healing factor but I don't think it's that much more powerful on Asgard.Regular Asgardians are harder to kill on Asgard under at least some writers though as JMS' run showed but like with all things, it depends on the writer. During Gillen's run, Asgardian's could survive without their vital organs for a surprisingly long time even on Earth. A regular Asgardian had his heart removed and held on for as long as five minutes IIRC, he would have been fine if it had been placed back.
Loki had his head cut off without any harm done but I'm not sure Volstagg has. At one point I do recall him sustaining an injury that should have been fatal without being the worse for wear though. IIRC, it was a spear to the head/brain area I think.
I'm not sure why regular Asgardian would get a huge boost to their damage soak but not Thor. I mean, if Brunhilda had impaled him through the chest like that on earth, I would expect for the fight to be over, or at the very least for him to be significantly injured.
Thinking more on it, it's possible that Volstagg only survived because his severed head was given a piece of a golden apple, but he definitely had his head severed. Does that sound familiar to you?
