Nice tip for EGR disable
If you're like me and you don't want to contaminate the fresh air/fuel mixture with burnt exhaust gases anymore then you have a few options but the simplest and most cost effective (free) solution is to simply flip the exhaust crossover over (turn it around) and bolt it back on, it effectively blocks the holes in the back of the heads, then don't forget to block off the pipe going to the EGR so it doesn't suck in fresh air and lean out the mixture. Didn't cost me a dime but if you want to remove all that stuff (which i intend to do) it does require some extra parts and RJM Injection Tech — Welcome has everything you need, their parts are not that expensive but the shipping rates are ridiculous..

The crossover tube in the rear is the Thermactor fresh air injection supply line, it's not part of the EGR system. The EGR can be plugged by threading the hole in the upper intake behind the EGR valve and inserting an allen pipe plug (3/8"NPT) in the hole This though needs to be done with the upper intake off the vehicle so the filings can be cleaned out after threading the hole. I'm lucky in that my 96 never did have a Thermactor system.

good info, i am in no position to R & R the upper intake so next on the list is EGR block off plate and harness pigtail from RJM that tells the ECU that the EGR is closed, could leave the valve installed but not sure if it is sealing correctly when closed and don't want to take the risk so off it comes in due time.
