Yep if the head chamber capacity* is 42 cc, then your CR will be 10:1.
I calculated for someone else a few days ago that a 2mm head gasket would drop CR to around 8.7:1. I honestly can't be bothered doing the calcs again for a 3mm HG (particularly on an empty stomach)...I'll see how I feel after dinner. 
* By head chamber capacity, I specifically mean the volume within the head. All you need to do is find a 1JZGTE head, get a small sheet of perspex, drill 2 holes (one to let out air and one to fill). Seal the chamber with the perspex sheet (use some Vaseline), then using a burette or a syringe, fill up the chamber (just use some colored water but be sure to dry thoroughly and hit it with some WD40 when you are done). When it is full, that is the head chamber capacity.
