You can plug the hole in your in take with a rubber plug which i have done can't remember the size off the top of my head but i'm sure if you do a search you can find it in doing this you eliminate the egr and will get an SES light if you can live with that or will have to get a tune or sell those and buy a new set

Rubber plug won't do it. Block off plates are very common, you could try a search for them. Basically cut out a sheet of metal the shape of the port, cutout some generic autozone gasket and bolt it shut.

Better yet install the 2001 intake and add 10hp to your header swap.

I thonk he was talking about the LS1 intake/EGR block off thing, not the header block off plates that you're referring to.

The intake freeze plug thingie is 1 3/8" I think btw.
