Im replacing the body mounts in a 79 k5, and the four mounts behind the wheel wells are tack welded to the bed. would it be faster and easier to raise the body the aprox 6" off the frame or cut the welds and pull the bolts up?

I used a grinder,and grinded off the heads of the stock bolts. Then punched them out with a BFH,and a punch.
the welds are really easy to cut with a grinder, just grind down the weld and pull the bolt throught the top. You might want to think about going with a bdoy lift while you are doing all that work
It's also handy to grind a screwdriver flat in the head of the bolts for re-install. Make sure you get the welds, as you will rip the body if you try and punch them out with even a small bit of weld left. How do I know? 
The screwdriver flat helps when you have two people, one can sit in the bed and hold the bolt in place so that it doesn't lift up, and doesn't rotate (again ripping the body since it's a carriage bolt) while you can be underneath tightening away.

too late, i pulled the carpet out last night and found some rust along the tailgate so the 2 bolts in the rear got buchered because some of the floor is going to have to be replaced anyway. the 2 above the axle came right out after i cut the spot welds, i was figuring on re-spotwelding all of the bolts after replacing the rust
