While your intake is off, re-wrap wiring harness so it overlaps passenger valve cover. Will make future removals much easier. Since you're replacing so many O rings, don't forget distributor, dip stick, oil filler neck, and cold start tube. My Renault re-engine has no Lambda (no port), yet I bought the car with current Pennsylvania emissions sticker. PRV may burn clean enough without it. Of course you've got no converter, so don't know if you can do away with both. I still maintain stock motor can be de-Lamda'd. Not only would that limit fuel mixture variations to CPR only, but would allow removal of O2 sensor in exhaust flow and computer from electrical load (if dash gauge is to be believed, my stock alternator puts out 13 amps, well 12.9, even with compressor engaged).
