Good advice and info so far. I have all the same problems you've explained but the solutions have involved multiple changes...Unfortunately, its usually not just one thing...its the whole combination. I might suggest port and polish on those aluminum heads and for a couple hundred bucks, get a single 4V intake and a Holley 750 cfm carb. Port match the new intake and slap it all back together. Buy some good header gaskets and consider having a new set of bigger headers fabricated. Dyno it again and see what you get? This, to me, is what makes it so damn fun owning a Cobra...
