compression ratio

I want to know what my compression ratio is on my ls/vtec setup I think I am doing something wrong. cause I am getting 10.6.1

setup is ls b18 block shaved .010 for decking the block, ls eagle rods, gsr CP pistons 9.0.1 compresion ratio. b16a head shaved to .40 came off a N/A car it has 5mm oversized valves, stock LS head gasket.
can someone help me figure out my compression ratio?

Re: compression ratio

without the dish.dome specs of the pistons, it is impossible to calculate.........yes I looked on CP's website.

Besides, if you took .40 off the head, valve seats wouldn't exsist!

using 30mm compression height, ZERO dome/dish I get 12.08 compression with the .050 total millage.
