AC are the OEM spark plugs and they are excellent plugs. I would recommend you buy AC/Delco Iridium Spark Plugs. They are as good or better than any others you can buy. NGK are also great plugs and I have been told they make the AC plug but I cannot verify that.
The recommended spark plug gap, for your 1994 Chevrolet engine, is .011. Most spark plugs will come from the store pre-gapped.
You must remove the plastic resonator box that says "Vortec 4200" on the top of the motor to see where they are. After you do that you will see 6 spots where you must unbolt the coil packs and lift them off the spark plugs. The spark plugs are down inside those holes. Use only AC Delco Iridium plugs. www.trailvoy.com

No, but burning oil will give you bad spark plugs.
