Re: egr plugs??
I had a friend who runs late model stockers build me a block off plate for lower intake....thats really all you need.
from my understanding, when you remove the egr, you need to reprogram the pc as there is supposed to be something in the ecm thats plays with the timing when you have egr.

On the intake manifold, remove the EGR valve and put in a block off plate like LVZ2881 suggests.
Put a cap on the one air nipple on the plenum for the EGR valve vacuum hose.
There shouldn't be any other openings on the plenum for the EGR valve. There are other nipples for the FPR hose, MAP sensor, PCV, etc.
