Moving engine to gain header/steering clearance

[RussMcB]

I've read a few posts that mention "centering" or shimming the engine to gain clearance between the header tube and steering tube.

Any suggestions from someone who's done this?

I have OBX headers. I dimpled the tube for clearance, and it's probably okay, but I can see they have touched each other since the install.

I can envision shimming the the driver's side engine mount to raise that side. I'm not as clear about how to "center" or move the engine. Would that be, loosening the two lower engine mount nuts, then using a 2x4" or something to persuade the engine towards the passenger side? Would the engine mount holes need to be filed a tiny bit to allow the movement?

Thanks, y'all.
