I know edelbrock makes one. For non egr intakes. what the do is just put a block off plate were it would be in the intake. Id surch edelbrock for it cause im shure they would sell it by it self.

What it does ids yoy just remove the egr valve and bolt the plate on it.

Take the EGR off of the manifold and make a flat plate to cover the holes. The EGR takes gas in and out through the holes in the manifold. Don't forget to cap off the vacuum source.

Don't forget, if you're using a carb that's calibrated for use with EGR, you'll likely get some part-throttle pinging if you ditch the EGR.

My EGR had a spacer that went between it and the intake. I used it as a pattern to cut a blockoff plate, then put the spacer on top of the plate to strengthen it up. I then bolted the plate and the spacer in place of the EGR valve. A thicker plate would have worked better, but I used the only metal I had.
