I have a '94 and I didn't use heated 02 sensors. I had 02 bungs welded halfway down the collectors and installed the stock pre-cat 02 sensors in them. I had PCMforless delete the post cat 02 sensor then I just unclipped it from the wiring harness. This is for a no cat setup. It works great and I really liked the tune from PCMforless.

Some folks have a problem with staying in open loop, especially at idle, with a non-heated sensor. A heated sensor is no a big deal so I put one in along with the headers. Try it unheated if heated is required you can always add one.
