Nope. You're stuck with FE heads and intake unless you change the rest. Rather than jumping into a new set of heads, perhaps pulling yours and checking them out? You may find your problem without even pulling the heads, could be a bad spring on a rocker. Try doing a compression test and see what comes of it.
BTW, in running like a dog, what's it doing?
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
