What injectors would you guys suggest,
And when under the plenum, what should I replace at the same time to save coming problems.

I also suggest the Delphi injectors over the loud, annoying Bosch III. More expensive, but worth it. I'll never install Bosch III on another third gen again.

When I did my 86 Corvette injectors, I replaced the thermostat (180*) , EGR Valve, Fuel Pressure regulator diaphragm, fuel filter, while I had it apart. I knew from the previous owner, it had water in the fuel tank, so I cleaned tank out and removed the injector fuel rail, disassembled it, replaced the O Rings and bead blasted the rust, off the pressure regulator housing. (FWIW I did plugs, cap, rotor, wires, PCV also, but you certainly don't have to do that).
I will be doing the same job, on my 89 IROC Z 305 TPI Vert, soon.
