Carb/Gasket sealing problem

[Blue71]

Working on a friends Bronco (made from several years) and noticed that whoever mounted the carb to the intake, used stock 2100 style gasket and it leaves a gap on the passengers side. I could hear it ticking when the truck was running. Not sure what the intake is from but it says D7 (77) but not sure if it's from a stock Bronco since it doesn't mate up perfect with the 2150 square backed carb, therefore the gap. It does have the flat back mounting surface like a later 75-77? 2150. However ....the intake has a protrusion on the passenger side so it leaves a gap in that area and won't seal. Can't remember if that's stock??? Any idea why this is this way? Even if I use the proper square backed thin paper gaskets that should have been on there and the 1/4 thick square backed gasket, it still leaves that side gap. Also...what would be my best bet at getting rid of this gap or sealing it up without removing the entire intake and going with a stock Bronco intake?

Thanks,

Here's the gap....

Here's where it's blowing out rather side where the protrusion is on the intake....

Your missing the EGR plate, and not using the correct 2150 gasket.

Clarrance is exactly right. The carb gasket is also correct, but it goes between the EGR spacer and the carb. Another thin gasket goes between the EGR spacer and the intake. All stock EB intakes from '73-'77 had EGR. The most sanitary way to get away from the EGR is to get a 289-302 intake made before '73. The easiest way to do it with your friends '77 intake is to get the EGR spacer clarrance showed you with the '77 EGR gasket set. Then get an EGR block off plate that covers the rear facing gasket surface where the EGR valve would bolt on.

Is there a place to get the right gaskets for the EGR so it confirms to the base of it?
