So I backed off the torsion bar tension, loosened the transmission mount, lifted the motor with an engine hoist, and loosened the k-member. With all that stuff loose I was able to shift around the K-member and motor slightly and get a little more clearance with pitman arm. I ended up putting a shim on the drivers side motor mount and that did it. Now the pitman arm clears the header by about 1/8" and I didn't have to dent my headers!
you still have to be careful because at extreme conditions, like hairing it up around corners, it could still bind up and momentarily lock up your steering linkage. It may not be an issue for you, just be aware so you're not surprised.
