thanks for the pic Justin. looks like you engine sits quite abit higher than mine. what motor mounts do you have? judging by your pic i'm gonna have a problem getting that tube to clear the colume.
If your engine isnt in the stock location you might as well modify the headers you have and save the money.. you wouldnt find something thats gonna bolt on unless you get real lucky

The Hedman's main advantage is the straighter section of pipe coming off the flange, doesn't have the compromise of having to install fit easily into the oem engine compartment. It makes more difference than you may otherwise think.
Nascar header expert told me a few years back the Dodge cup motors were making more HP than the chevies and fords on the dyno but when they made headers to fit the chassis (mopar had a slightly differnt port spacing configuration)the additional/tighter bend radius caused the peak hp to drop considereably.
I saw about the 30hp difference, what heads were they and what RpM and cube was that? I could see that if you had a fairly big (slower velocity) port where it needed the straighter tube to get it flowing, likewise a cam with maybe comparatively too much duration/overlap might have a harder time in the upper rangers with the tighter TTI's. I know TTI only recently upped the collector to 3 1/2", 3" is really small for any 400" motor above about 4500 rpm, by capping the torque peak RPM you by default also lower the hp trajectory compared to the optimum sized collector.
