They probably weren't the 9:1 pistons.  But you can tell with a piece of
wire.  Pull the sparkplugs out so the engine rotates freely.  Take a length
of soft wire (copper is nice) and insert it into the sparkplug hole of your
choice.  Rotate the engine until you can move the wire around over the
surface of the piston pretty easily and thoroughly.

What you're after is feeling a dish.  The 9:1 piston is flat faced, and the
others are dished about 1/4".  You can feel this dishing pretty readily this
