Adding so called "performance parts" is something better left until after the engine is broken in, and properly.
Trying to up performance before you even known how the engine performs is just asking for trouble. Burn at least a few gallons of fuel, about 200 miles worth before changing anything. Then you'll know what you might need in the way of help.
The biggest problem with these "high performance, "speed" parts is that they are questionably helpful and can add to the performance issues that you'll undoubtedly have until the engine has run a few miles and you've checked spark plug color and seen what your engine is asking for.
Run it stock and wait before wasting your money.
