I bought an Edlebrock Performer intake to put on a 1984 Dodge 360. The intake does not have a provision for the exhuast crossover and I am at a loss as to how to block the holes in the heads off. Thanks for any help that you can offer.

No crossover on a performer? I have never seen that but I have only seen a few. Dont do anything. But if your on gas you better get an electric or manual choke setup.

I assumed it was the heat crossover, but maybe it is something else. It is a half moon shaped hole on both heads right in the middle. Edelbrock told me that it was some type of "exhaust expansion port" and it didn't need to be covered, but I would like to verify that before I crank the motor. Thanks for your help.

I have the same setup. Edelbrock Non-emmissions intake on 360 with older non-emissions heads. By non-emissions I mean they don't have the little ports beneath the exhaust holes that go to an air pump.
The only problem I have noticed is a bit of oil like residue that forms on the intake manifold between the inner two cylinders on both sides. I'm not sure if this is from the U shaped port, nor am I sure why the discoloration forms.
Other than that, it runs fine with no vacuum leaks or other problems.

slap it on and forget about the u-shaped holes on both sides / its a air cooling port for the cross over
