I just went through this process with a lot of help from guys on this site. Most recommended heat, but I was too much of a chicken to light a torch in the garage where I was spraying PB Blaster like aftershave.

Here is what finally worked for me: Drill holes in the stud / nut using the drills that came with the easy-out set from Lowe's. Tap the easy-out into the stud. Use a socket extension to drive the easy-out as it disappears into the heater box hole and cannot be turned with a wrench or vise grips. I had to wedge tye-wrap plastic into it to allow me to extract the easy-out and the extension once the stud came loose. Use the longest breaker bar available to put torque on the stud while pushing down on the stud.

Swear creatively.

Walk away when you get the urge to smash the heater box with a large hammer.

It took me about a week to do this. A real porsche mechanic probably could have done it quicker.

Final score: five barrel nuts came off normally, five studs came out, two studs snapped and will require work by the machine shop.
