OK so i got an extra kegger today. Figure ill mod it put a new gasket on it clean it all up and put it on my niner. It was free so i took it BUT it is an EGR kegger. It's already got what looks like a production off the shelf block off plate. Doesnt look home made. My question is this, can i remove ALL the crap inside it that was used for the EGR? That giant port that runs half way down the middle of the manifold? If not, im going to look for another manifold. Kinda pointless to do a half *** mod. Lastly, this manifold came off a 318 in a 1996 ZJ obviously at some point the motor was swaped out. Is there any way i can figure out what year manifold this is? Maybe ill get lucky and it's a 93! Exhaust manifold time! As always, thanks for any and all info.
