Be careful not to fall into the trap of a bigger build= higher compression= higher heat and more temperamental.Especially if you are spending a lot of time sitting in traffic, which you indicate that you do.
Sounds like you are thinking since you have oil consumption you want to pull the heads and freshen some parts up. Good idea because these engines are known to burn oil because of cylinders that go out of round and poor piston rings, plus some argue full synthetic oil adds to this.
Another option is to keep it a 110 and add mild cams and maybe just a thinner head gasket to bump the compression a bit but keep it under 10:1. That plus a good exhaust, and a great tune. While you are doing that, refresh the valve guides, umbrella breather valves, lifters, etc. You will end up with a much better and cooler running engine.
Having said that, since you plan to go to a reputable shop, get their opinion on what you need to do to accomplish your goals.
