I have successfully swapped a 5L HO from a '92 TBird into my '76 Bronco using the original Bronco intake and 30 year old 2Bl carb. Now I want to upgrade to an aluminum intake manifold and a new 4bl.

I would like to use a non-EGR intake.

How are the the exhaust ports from the heads blocked off ?

Would you need some special carbon intake gaskets or steel shims?

Also any suggestions re intake and carb selection would be very helpful (strictly low speed around town driving, no off road use).

No special work needed. All the smallblocks had those ports in the heads and aftermarket intakes accomodate them just fine. Just pick out a "non-EGR" intake and you'll be fine.
Personally I and very fond of Weiand Stealth manifolds. They are a "high rise" dual plane though. For just putting around town a low rise such as an Edelbrock Performer might serve you better.
For bolt on and maintenance free (almost) use, it's hard to beat an Edelbrock Performer. One rated at 500cfm is just right for a 5.0/302 engine. Holleys tends to need more attention, fine in a race car, not so great in a daily driver. My Mustang I play with on weekends has a Holley, my truck I need to drive regularly has an Edelbrock.
If you haven't already, I suggest looking into some headers. With your other changes they'll be worth another couple of horsepower. And even better a mpg or two.
