I am thinking going back to the oem 155/80/13 tire size will same me some drag/resistance.
OR
I can go up to a 185/60/14 and keep most of the spedo difference in check at .09% difference but the tires will get heavier and 1.1" wider which might reduce my efficiency/MPG and raise rolling resistance, un-sprung weight and other factors??

Forget the "narrow is better" approach. Not only has that limited your choices, but it is fundamentally flawed.
Put the largest tire that will fit without rubbing. Discount Tire might be able to help you. On their web site, they list alternative tire sizes after you input your vehicle. Find the size with the largest load index. THEN look at your choices.
