G3 Hemi TTI Headers and Borgeson Box - anyone running this?

[70chall440]

I am in the process of building my 71 Charger and will be running this combination. The header on the drivers side is very close to the adjustment screw on the steering box and I am wondering if anyone else is currently running this and if there are issues or not (such as the plastic in the nyloc melting out). I am using TTI motor mounts as well because they told me that the headers would definitely fit if I used their mounts (which they do). Number 3 cylinder is a real bear to get the bolts in with the box installed even with the engine on a table, I imagine it would be very frustrating in the car (I'd pull the box).
