How many miles on the bottom end. If you pull the heads off the motor you will probably end up rebuilding the engine if its high miles and never been rebuilt. I would be suprised to see a big block with perfect bores from 1979 and still perfect.

The heads are very heavy, alum heads will take a good chunk of wieght off the car. And will be bolt on ready AFR has some nice heads for 454. By the time you get the heads back you will have at least 500 to 1000 bucks in them unless they are fresh already. Between port work and new parts and replacing any burnt or bad valves guides and seats. You will not be far away from the price of great alum heads and get the wieght along with the large flow.
