I'm not a big fan of a header design that takes a very hot component and brings it up into the engine bay closer to the intake.

i am not familiar with the header.... how close does it come to the crank pulley?....as long as it is not directly in front by a distance closer than 3.8cm, there should be no problem at all.
BTW...Just finalized the 91 octane tune with stock header and exhaust
on our in-house rototest dyno the base kit made 251whp
on a third-party dynojet nearby the kit made 272whp and 218wtq
(dyno graphs to follow shortly)
for the sheer amusement of speculating...we anticipate the following gains
header+exhaust = +20whp
small pulley upgrade = +15whp midrange; +25whp peak (max rpm 7300)
E85 = +25whp
