Loss of power, alot....

Ok guys tell me what I think I already know.... I have a 1971 Pontiac 455 HO bored 30 over with a edlebrock 278 degree cam, 750 edelbrok carb. I got the engine installed in my Grand Prix and the Engine had open headers on it. Tons of power. I installed some glass packs directly onto the headers to get it to the local car show and there is a huge decrease in power. when I step on the gas it hesitates and "putt putts" when held to the floor. Before with the headers it would spin wheels till i let off it...Does my Carb need to be adjusted?
