Stock Exhaust Manifold Install & Removal

I am about to lift a 340 out of a 69 Barracuda that has stock exhaust manifolds. The is little clearance to remove them with the engine bolted in unless master comes off and a few studs removed. Drivers side lower flange hits the power steering shaft. I do not want to ding the fenders and the engine bay paint. Is there a preferred method to remove the maniflods/engine. Looks like they cannot be removed/installed bolted tot he engine. Should the engine be lifted slightly and then pushed to make the clearance? Passsanger side looks like the heat riser will scrape the engine bay if lifted.

Any advice to remove and re-install to keep the engine bay unharmed is appreciated.
