The cylinders that were in the engine were Alusil. Several measured out of spec and one was severely scored. I sold them to someone who thought they might be able to find a good one or two in the set.

I purchased another set of Alusils from Tom Butler who has quite a collection that he has properly reconditioned and matched piston/cylinder sets.

One thing that I just came across as I was checking the deck height of my pistons using the techniqued outlined in Wayne's book - i.e. putting a couple bits of plumber's solder at the edges of the cylinder, assembling the head then turning the crank past TDC to crush the solder bits. On the first one I checked, the deck height is measuring 1.8-2.0mm. I am using the copper shims that came with my gasket kit. I just checked them and found that they are 0.050mm thick. Like a fool, I left the copper shims on my original p/c set that I sold. They were thinner, probably 0.025mm. Looks like I need to find a 0.025mm set of shims.
