I've got the same serpentine setup on my K5. I don't have A/C but have a compressor in place to keep the system up (I need the a/c delete pulley). DirtyLarry had this installed this setup when the engine was in his K10. He was using the a/c and since the compressor location swapped sides from the stock setup, he got a couple of hoses that fit the compressor from the junkyard, cut the ends off for the compressor and took them in with his old lines to make new ones. They made a hybrid with the old fittings he needed for the evap and condensor, but with the new correct fittings for the R4 compressor. It was the perfect time to switch to R134a too.

He had to do the lines again when he put the big block in with the L29 serpentine setup as the compressor and alt swapped sides again.

Here's a tip when using the style of serpentine setup I have. Get the thermostat housing for a 88-95 truck and the upper hose from the same. This will change the position of the outlet on the thermostat housing to rise up and then forward, clearing the serpentine belt. Only difficulty is that the inlet on the radiator is slightly bigger that what the hose was designed for on the later trucks. Just a little dab of vasoline is all you need to slide the hose on the radiator.
