Ah thanks for the replies guys, would it be a simple matter of just swapping out my steering shaft directly for a flaming river unit for instance?..
Such as no extra drama or mods just disconnect from the rack and steering column at the engine bay firewall side, install the new shaft into my power rack, and I'm good to go? I appreciate the help, just need to know if it's truly that drama free.

Your level of success depends on what K-member/steering shaft combination your headers were originally prototyped to fit with. All the aftermarket K-members relocate the steering rack from the stock Fox body position, which in turn draws the steering shaft along with it.
A few examples of this would be as follows:
UPR 5.0 K-member- moves the rack mounting position up .5"
AJE K-member- moves the rack mounting position down 1-1/4" and over towards the driver side by 1/4" from the stock position. The engine is also moved closer to the vehicle centerline than stock.
Team Z swap K-member- moves the rack mounting position down 1-1/4" and over towards the passenger side by 3/4" from the stock position. The engine is also moved closer to the vehicle centerline than stock.
As you can tell, there is no standard engine, steering rack/shaft position used by all K-member suppliers, so a set of headers that works well on one user's car may have considerable interference on another user's car that is using a different K-member.

Anyone running the Speed Engineering Mustang LS swap headers? Thinking about ordering a set, but was wanting to see if anyone is running them already.

Do they fit with Maximum Motorsport K? I emailed Speed Engineering yesterday and asked if they knew if their headers would fit with a Maximum Motorsport K in a Fox. I was impressed that they got back to me within an hour or so, but sad to hear that they have not tested their headers with a MM K, so I'm wondering if anyone here has tried this? I'm running the MM 5.0 K, not the 4.6.
