Advice removing heads from 360

So I'm trying a big project outside my comfort zone. I've got a 1967 Barracuda with a 360, and I believe this engine has blown a head gasket, so I'm looking to replace them.

I've run into a problem where the headers do not give me clearance to reach the head bolts, the last one on the dirver's side in particular, even when the headers are disconnected from the head, and the Y connector.

It looks like I either need to remove the steering gear box and shaft, or disconnect the motor mounts and jack up the motor to get a few inches. I'd like recommendations on the best way to proceed.
