When doing a "half shell repair" you must remove the bolts holding the bank 1 exhaust sprocket.This allows you to turn the engine to facilitate bank 2 disassembly without spinning the bank 1 cams. If you lock the cams at TDC 1, then the valves all stay closed enough to clear all the pistons.

You can leave all of bank 1 assembled, even leave the intake manifold in place on that bank.Just remove the spark plugs.

Magnetized engine parts are a big deal. I was referring to shipping mag drain plugs with IMSBs, which is a huge deal.
