h/o output cams in 4.7L flex fuel motor?

I know that the h/o cams are a great upgrade to the regular 4.7L motor, but would the fact that my motor was built for flex fuel cause any issue? Second, if they will work fine does anyone have any h/o cams they'd like to unload?

Tuning beyond a power programmer? I really wish I could've gotten into the 2008 xk. They got over 300hp out of that 4.7, but it's a whole different setup so I can't really just "bolt on" any of those parts. I thought trying to at least get the h/o specs like my 01 Dakota would help this thing get up and go.

To really help this beast, intake, tuner, exhaust, ported throttle body. These aren't to bad to buy and DIY for any mediocre mechanical person.

I've already got the intake and tuner. Probably going to put a flowmaster 50 series muffler on, but what about the cats? Should I even bother with trying to make aftermarket high flow cats work or just put a cat-back system on and call it a day?
