Default 2.5l WRX hybrid...

Most can agree that it's the cams that hold back this combo. Some say the heads too. No doubt better heads can help, but how much? How much of a difference is a 2.5l wrx hybrid with STI cams vs. USDM STI?

I know there are other threads on this, but I haven't seen any that clearly state the difference of heads.

i heard that there is not much of a diff. from wrx heads to sti heads, moreso the cams. however that is what i have been told and i am not ready to consider it as fact.
