TTI 1 7/8 Headers hitting oil pan

May I ask how you pulled the driver side header? I'm I. The same dilemma as the OP

I put it a couple feet up on some 6 ton jack stands, pulled the Z-bar, mini-starter, and dropped the steering center link (and cycled the steering side to side depending on which side I was working on). I also pulled the torsion bars. By doing that I was able to pull the drivers side header without unbolting the mounts or raising the engine, the Milodon road race pan wasn’t an issue.

It’s in my build thread here, post #231
