engine mods??

I am looking at refreshing the top end on my SR185 this winter, since I am starting to lose a little compression, and run hotter than it should. My question is while I'm in there, is there something I could do that would not be ridiculously difficult to increase torque? I thought maybe I could have the head shaved down just the tiniest bit to get a very slightly higher CR than stock, but I don't know if that would help bottom end torque or just at the top end. I saw that renault_megane_dci is opening up his exhaust ports, would this be likely to net me gains? I will definitely be at least cleaning and polishing them up a bit. along with the intake. since that costs nothing and can only make the engine run better. any other suggestions would be good, just keep in mind that I have average mechanical skill, and fairly low budget. I do know a machine shop that does good work, for a fair price. and I could probably afford the head milling, or getting the cylinder bored, or something simple like that.
Thanks,
Ben
