UPDATE:

I put the new TTI drivers side header in. It fits MUCH better


The new jig header has improved #1 routing. It kicks further forward (towards the front of the car) before turning back. This helps it clear the Borgeson box in my car.


First Driver's side header: motor was sitting on the header on the Borgeson box. Situation was improved with grinding on the box and denting the header significantly. Motor was still sitting on header/power steering box (wasn't seated fully in motor mount). Ran it like that for ~4,000 miles.


NEW JIG HEADER: Motor seated all the way in the motor mount on the first try. I still dinged the new header in a couple places, but it probably wasn't necessary.


For those of you looking to use the TTI headers specific for the Borgeson box in an A Body, I say do it. Depending on your K frame, you might need to dent it in a few places, or it might drop right in. It is a very tight fit.


TTI also recommends elongating the mounting holes on the borgeson box to move it further towards the fender - I did not do this modification.


Notes on installing these headers in a 73+ k frame (spool mount A body): Drop the motor in place without the headers in the car (and without the steering shaft coming into the engine compartment). Next, put the borgeson box in place, but don't bolt it down. Lift the motor up a few inches (leave tranny attached to car), and work the headers in from underneath. Having the borgeson box loose will make the job a lot easier.


Big thanks to Peter Bergman of Bergman Auto Craft for taking care of me and big thanks to TTI for sending the newly jigged header.
