Do I just need the block off plate or is there more to it? Where can I get one? Reason im removing it is because I have some 82-92 headers and the LT1's EGR line goes to the exhaust manifold not to the block like our motors. Thanks.

i make them from a piece of sheet metal, 11 or 16 ga and a gasket

Just need to make one where the tube goes from the intake manifold right? Considering I don't have to block it off from the exhaust manifold, or is there one im missing?

If you're putting on headers that don't have EGR then dont worry about that end. There is one on the back on the intake that you will have to block off right beside the EGR valve, which I would block off too. I've used 1/4" steel for mine.

Thanks Texas.

I made mine out of a $.19 electrical box cover. It's thick and easy to cut with a dremel. I used some RTV and it works perfectly.

A friend of mine (machinist) is making 1/4in. aluminum blockoff plates and selling them for $25, drop me an email if youre interested.

LoL, no offense to your friend, I know were all out to get money, but uhh, not for no 25 bucks.

Its cool, just thought Id give you another option.

if you have headers without the egr hookup then you only have to cover the upper square hole right under the egr valve. No need to cover the hole where the tube hooks to the manifold if you block off the top hole under the valve. I leave the other 2 holes open, if you cover them you're just trapping hot air inside the manifold. The easy way is to loosen ther egr valve, then slide a thin piece of metal between the valve and manifold to cover the top hole, then clamp it in place with the valve. If you really like the hacked ghetto look you can whack the diaphram off the valve.

I didn't quite understand what you meant in that reply.

which part?

Upper square hole under the EGR valve?

remove the egr valve, there's 2 holes under it. The square hole on top is all you have to plug up. Just put a little piece of metal over it and put the egr valve back on top of it to hold it in place

Oh cool, so just do that and leave everything else as is?

This is the one I was talking about blocking off:
