That is pretty much the same build I have.
FATCAT w quiet baffle and street ported heads (not that expensive) plus TMAX (expensive) are the main differences: I am very happy right now.
In the beginning I was experiencing a kind of short breath ot these cams past 4K rpms. After 1K miles I've seen some autotuning in the higher rpm range that somehow made it better... or maybe I just got used to it.
What really matters is where u mostly play the throttle: I love lower rpms pull these cams deliver, and I can live with some lazyness in higher occasional revving.
Just my .02.
