Well, looks like the only thing changed is the mill, unless they did some chamber work on that head so...
0.10 inches? Cause that's WAY too much. Maybe you mean .01" or 1mm. If it is indeed .10 inches, tell us how that goes.

Here's one calculator: http://www.zealautowerks.com/hfseries.html

I take it you mean .010" head mill.

What is your new piston CC since you're boring to 90mm on sleeved F22 block?

That price includes the 4 custom pistons, 4 XHD 4340 piston pins (for durability with the high boost level), pin fitting, lock removal indents, spiro locks and plasma moly file fit piston rings.
