Nice one!

Especially because some have had a right bastid of a job shifting them, involving; swearing, pain, tears, breakage and spark erosion.

Whilst it's apart, see if you can see the oil gallery plug in the side of the crank as they can back out, hopefully and probably it'll be fine but it costs nothing to look down the side of the crank with a bright light.

On reassembly make sure you fit all new 'O' rings in the cylinders/heads and seat the base gaskets with threebond (but not too much or you might block some oilways).
