Agreed with Vadim.... Start a new thread, completely different topic and I have some questions that I need answered to get a better idea of what is going on with your car and don't want ot clutter up this thread. To the OP... You can safely run your car on 19* base timing, even with 9.5:1 compression, so you will be just fine with the 8.5:1 and that should get you where you want to be mpg wise and pick up a few ponies also. I understand that you don't want to chance anything on your engine but the All Data +or- 2 is considering that you are running 87 octane fuel. When running premium fuel 19 or some even go up to 21 is not an issue.
