CG 230 cylinder head
Would a cg125 cylinder head work on my brozz 250?

The spacing for the cylinder studs should be different, I don't think it'll work. Where are you located?

Why a CG125 head? Why not buy the Brozz250 head?

That's what welding is for! If you had a 200, it would work, they changed the stud spacing for the 230.

Just mill the stock head down to increase the Compression Ratio.

2 local shops quoted me less than $50 just to mill one down. And the Brozz (and TT250) head appears to have the best factory ports compared to all the others.

Ultra budget compression increase, remove the cylinder base gasket and seal with a semi-hardening gasket maker. Just make sure to not block the oil passage to the head. Then replace the head gasket with a TT250 single layer steel unit.

I took measurements with a straight edge and feeler guages then used a $25 handheld belt sander from harbor freight to deck my head. Just gotta keep rotating it with very light pressure to avoid removing metal from the wrong areas.

Does that give the same results as shaving?

Removing 1mm or 040" will bump you to 10:1 CR. You can easily remove that with sand paper on a flat piece of steel or glass. Lots of elbow grease and rotating the head every so often to make sure you are removing it evenly. I've done a few. A bench top belt sander will make quick work of it. That's what i used back in the day to shave down outboard heads for racing.
