i think i burned my valves

Open headers on shorty headers is a big no-no. But if you damaged the valves your car wouldn't even be running. I know this sounds too simple...but what your describing (miss at 4K) sounds like a tune-up problem. When was the last time the car saw new plugs, new fuel filter and clean the mass air meter?

so I put my bbk long tubes on and i raced a 2004 mazda speed protege and i left off at 80 and was a good 3 or so cars ahead of him. So a few months later my car feel rather slow to me so i put in some 3.73's. Re race but have the h pipe on and lose about a car and half and that wasnt even a full 1/4. My car also pops super bad at higher RPM and doesn't pull at all past 4k. So I figured why not go ahead and get some need heads. I'm thinking either of getting the afr 165's or the trickflows. I'm not sure which i want cause i've heard a lot of good things about both. I think while I'm at it i will be doing a cam swap. I was looking at the stick on the cam specs and i think i might go with a Crane 2030 but if anyone has some better ideas on combos that work well let me know
