I had a mid 90's Z71 too, great 4WD truck. Mine had about 200k miles when I sold it. Have you tried to use some "non foulers" for the fouling plugs? You can do each bad cylinder for about $5 and it is a very simple ~2 minute fix per cylinder. It may very possibly extend the life of your engine for a while. I've used the trick/fix on some older vehicles that I didn't want to do an engine rebuild on and it's worked for me a number of times.
Rust holes just add character to a work truck.
I gave them a thought. Might go for it (them) to try and get it past emission inspection. Getting a bit tired of resetting the misfire codes. Agree the rust holes are genuine macho backwoods glory.
Btw I had used them on rear O2 sensors to fool the 'puter about catalyst efficiency.
