Why would you want to block it off? Just disable it. It looks the same as the 87 so you could probably use one of those plates. Doesn't BFH make some engraved ones?
the reason i want to to block it off is because the intake has been cut and rewelded inside and it block off the egr so i want to get the ugly valve off the top of the intake. and the egr port isnt the same as the 87 there 2 different shapes.
