Default LFA compression?!

Quick question for the experts:
How does the LFA (6.0L) build a CR of 10.8 ?
The pistons are different part numbers to the L76, so are the heads.
Are the pistons flat top or dished or domed?
Part number for the LFA pistons is: 19168016

Precisely! 4.00" bore and 64cc chambers! It's a VVT engine as well, I believe.

My pistons had one valve relief in them. Can't remember if it was intake or exhaust. Anyway we flycut for PTV issues and to lower compression a little with my Trick Flow 220 heads that are cut to 59ccs.
