Changing engine mounts with engine installed

so I had 318 mounts installed backwards on my 340 and it kinda worked for years but eventually wore one of the biscuits out. I think that I could push straight up on the passenger side but I lifted farther forward on the driver side. I needed to tilt it back to get enough room and not disturb headers/steering/starter, linkage& cooling lines. But I watched all that pretty close as I lifted.

Edit I bet I had removed the nuts on both mounts first to allow the motor to twist more freely.
