Am I ok with this? KB107 in La block

Ok, so I have put pistons in all corners.
I have remeasured ,
Cyl 1 is about .014 down , cyl 7 about .014 down
Cyl 2 is .008 up and cyl 8 is perfectly even with the deck.

The same piston/rod in all 4 corners.......or 4 different pistons/rods in the 4 corners?

You could run two different thickness gaskets to get the two sides overall deck clearance closer to each other.
Cometic offers .027 and .040
