Im surprised you did that well, those 99+ stangs can be strong on top end, especially when you get a good driver, even i've had some close calls with the topend runs.
My suggestion, aluminum heads, or a bigger valve iron, with port work, and good valve springs, also the cobra intakes really respond to porting, but by the time you spent all that money on machine work, you could have already bought a supercharger.
