Ok, here's what I've concluded on;

- The 9.4:1 piston has a slightly dished crown (increases the CC volume by 1.6cc).
- The 10.0:1 piston has a similarly domed crown (decreases the CC volume by 1.6cc)
- The 10.3:1 redtop piston has a similar crown to the european bluetop one, but with a slightly higher dome (decreases the CC volume by 3.0cc)

Below are some photos for illustration - you can clearly see the difference between the 10.x:1 ones and 9.4:1 ones because the centre of the piston's crown is actually recessed below the rim of the crown.
