I had a spare EGR gasket and just used it as a template on a wall switch cover plate using a sharpie black marker....cut out with tin snips..used a dremel to deburr...center punched & drilled out the two bolt holes and voila. I left the EGR gasket stuck to the base of the EGR and reinserted the two bolts..then slid the blocking plate over the bolts & put the extra EGR gasket (came with Supercharger IIRC) under plate and then set entire assembly back on mounting face...tightened bolts. Easy job and completely reversible if need be.
The only thing I'm concerned with is keeping an eye on the oil usage as in theory the cylinder temps should be higher since you are now burning (exclusively) air/fuel without reburnt exhaust entering the picture. Took it for a test drive & no check engine lights as EGR is still connected to plug.
I'll take a quick pic and post.
