Help please

i HAVE A 2000 TA AND I HAVE A MS3 CAM, PATRIOT SPRINGS, HARDENED PUSHRODS HEADERS, STOCK LIFTERS, AND STALL AND THE CAR IS TUNED BUT HAS A SHITTY TUNE. WHEN I HAVE THE CAR ON IN PARK I CAN HEAR A TICKING SOUND AND WHEN I GIVE IT GAS IT DONT GET LOUDER IT GETS FASTER BUT AFTER ABOUT 2K RPM I DONT HEAR IT ANY MORE. I DONT THINK IT IS A EXHAUST LEAK CAUSE YOU CAN ONLY HEAR IT WHEN IT IS COLD AND I HEAR THE TICKING SOUND WHEN THE CAR IS AT ABOUT 190 DEGREES CAN YOU TELL ME WHAT IT MIGHT BE PLEASE.

I wouldn't run anything less than 91 octane. That's probably just spark knock from the lower-grade gasoline.
