I'm going to replace my front wheel bearings and while I'm in there my pads are getting ready to be replaced and since I'm already in there I thought I would go ahead and replace them . My rotors are fine except for the wear from the brake pads. Can you turn 80 rotors or do you just buy new because its such huge heavy truck the heat will wrap them if there turned?

Turning rotors is false economy IMHO. One of their main functions is a heat sink and removing material decreases the amount of mass, obviously, leading to increased potential to warp (like you mention). Unless they are badly scored or gouged (or anywhere near the minimum thickness), I usually just let them and new pads "get to know each other". It really won't hurt anything. If there is any doubt - I'd replace them. The cost is miminal compared to having to pull everything back apart...
new rotors are cheap, like $30/ea. it costs at least $10/ea. to urn them, does not make sense....buy new.

There is that whole debate about ome and what not. $30 has anyone replaced the stock rotors with $30 rotors and had any problems?
if you are using OEM pads then stick to OEM rotors. if you go aftermarket rotor, use their pad with it. each company designs their metal rotor and pad together.

Ahhh good to know I want to throw 100 series pads on so I guess ome although the ones on there are just a little scored
they are raybestos lifetime rotors. never had any problems.
If your current rotors are in good shape there is no way I would replace them with OEM rotors just to put 100 series pads on. If they are good then just put the appropriate new pads on and go. The gains if any are minimal and over reported.
I have yet to see what the size difference or quality/benefit there is to running 100 series pads on a '91-97 80 truck, when I can't see how you can even fit anything physically larger (surface area wise?) in the caliper given how it is designed to fit only 1 size with only so much room...

The backing plates of the pad are the same size but the friction material of the 100 series pads is larger taking up more surface area. The pad material is also thicker not allowing space for the anti-squeal shims. You do get better braking performance and longer pad life.
If you don't turn the rotors you get some excessive wear until the surface of the pad matches the surface of the rotor.
In my case the cost of turning rotors is 0 dollars because i have a friend who works at a machine shop.
when i do front axle service i can just take them to his house, he'll take them to work and media blast all the rust off and then turn 'em for nothing.
and i can then probably use the anti-chatter shims on 100 series pads.
