www.projecttransam.com has a how to guide on !AIR and !EGR i believe brent does too. You can either order the block off plates off the forum or if you can weld take off your old egr tube and remove the tube from the bracket and weld the hole up on the bracket and restall it that is what i did.

I found this guide on Brent's site, I'm not sure what year it's for (or what year yours is for that matter) but it will give you some idea. I made the two little blockoff plates, the one for the exhaust manifold and one for the back of the intake where the manifold tube runs to. I made them out of a piece of 1" wide 1/8" thick aluminum stock (got at Home Depot). Just trace the gasket to it, cut it off, shaped it with a grinder & drill the holes. The bigger plate that deletes the valve was a little harder to make, so I just picked that up at the dealer for like $7 I think. 96 - 6spd Corvette EGR delete plate. Depending what year you have you may get an SES light with it gone.

i realize you don't have egr on your headers mine isn't hooked up either. I was saying once you take the EGR tube off the back of the intake you can cut the tube in half and slide one of the brackets off. It looks like this (o 0 o) then you weld up the middle hole and put it back on. So it looks like this. (o o) I think you can just leave your EGR valve on. What i did was take the valve off and cut a block off plate out of house flashing and bolt the egr valve back on with the flashing in between the intake and the valve. http://www.geocities.com/MotorCity/6...3/egrpipes.htm

So if you dont have to block off the exhaust manifold in the case of non-emissions LT headers all you need is the LT4 EGR blockoff plate on the intake manifold or something like it and nothing else?

If you dont have a connection on the exhaust then you would have just the two connections to block off on the back of the intake.

I took off my EGR tube and plate that goes into the back of the intake manifold and cut the tube pretty close to the plate. Now this is ghetto, but it works, and no one will ever see it I took a hammer and smashed the tube down so the end was closed. Then I gobbed RTV gasket maker on it and wrapped it in tape. Then I bolted it back on So it still has a little of the tube sticking out, but I garauntee it doesn't leak, hehe.
