As others have stated the running terrible is not caused by low compression in your case. 110 is not that low and they are even, so solve the other problems first. There are several tech articles about extreme wear in piston engines and the conclusion is that they can be run until the compression is so low they will no longer idle. I've seen engines run with numbers as low as 60 and once warmed up they run fine, of course they don't make the power they should.
If this was my engine I'd leave well enough alone and find the real culprit to poor running then only if I needed more power would I open the engine up.
