Horsepower limit for out of the box Edelbrock RPM heads

Yeah my wife's DD is a 2014 Chevy Orlando 2.4VVT with a 6 speed auto. Orlando is a crossover/hi-roof wagon.It appears to be a 108wb/3650 pound unit, just like my Barracuda. And if I wind it up (6700 redline) she rockets thru 2 gears and does pretty good in third too. When I go to pass someone, it kicks down 2 cogs and and the VVT comes on line; moving her out fairly briskly. And the 65=2000rpm makes ~32mpgUS,which is easy on the wallet. I never notice the dead at 65mph, cuz it kicks down at just the right amount of throttle, yet never hunts for loc-up.
Nice combo.
But the heater blower motor just cost me $195C, and the control module for it was $159C. Easy installs tho. And the stinking cartridge oil filters cost $9C apiece! The cabin filter was $80C,yumpim-yimminy.
But I thought I was pretty smart; before I drove it off the lot, I got the used car dealer to throw in a spare set of 15" mags and 4 new tires. 15" tires are cheap. So I should be good for 5 or 6 years on that score, which will put me into my 70s, hopefully retired not driving much anymore, if the world makes it that long.
