Mazda FS-DE Asian Spec (Australia) Compression Question

It's my first rebuild and I'm doing it redneck style in my shed, minimal machining, fresh rings and bearings, but I'm thinking of having the head faced (I did check it with a couple steel rules and it looks perfect to me).

I wonder if anyone on r/EngineBuilding knows how I can up the compression on this engine WITHOUT using the FP-DE or FS-ZE pistons, just skimming the head?

Stock compression for my market is 9.7:1 and I'd like to get to about 10.4:1.

This seems like a better sounrce of knowledge than facebook and the forums I've searched don't really seem to have the solution.
