I have a 1994 F350 CC 7.3 IDIT. With 130,000 miles. I am thinking about changing the head bolts to studs. My question is can I just pull one head bolt and swap to a stud one at a time or do I need to pull the heads?

 

One at a time is possible, if you can get enough clearance around the motor to do so. You may or may not need to disconnect a motor mount and jack the engine, or remove part of the AC/heater housing to get enough room.

 

I was wondering the same thing. Let me know what happens. I have an 87 f350 so I assume its the same

 

Been curious about this too. seems someone over on oilburners done that.
