CR for Frankenstein Build

[Granny]

I'm trying to figure out my CR for my Frankenstein build. I have a 96 2.2L NA block with 25d NA heads. If you have measured either your 2.2 block or 25d head combustion chamber please post what you got. Thanks in advance.

Edit: pretty sure the heads are 46cc, and CR should be 8.5-8.7:1

Thanks for your help.
