While I agree that headers will make a power difference, I find it hard to believe that there would be a signifigant enough restriction to cause engine damage. I can understand a 500 inch carb. motor with huge overlap having a big enough problem to cause what you described (I had a 406 sbc with enough overlap that without a race carb it would overscavenge the cylinder and run lean with a 1050 dominator jetted so rich the car wouldn't even idle). Were using a car with a carb. relying on a fuel metering from boosters and juts to a programmed, fuel injected car tuned for this particular setup. That's a little apples to oranges don't ya think. I know you are light years beyond me when it comes to these car, but do you really think I will hurt the motor because I don't have headers with a big cam?

Not sure how possible that is since Jets don't affect the idle on carbbed engines because you are still just using the idle circuit. You can essentially remove the jets and leave it like that and have "mega jetting" or whatever and it still won't affect idle. Sounds like maybe u needed to do some air bleed tuning as well especially with a dominator. My 1150 3circuit gave me headaches before when I first started tuning it. these carbs can be finicky sometimes since these carbs were originally designed for max power at wot and high rpm off throttle.
