Aluminum heads would be a great upgrade seeing that you are going closed. And would help with detonation issues should the temps increase.
Good luck and keep us posted with what you find and how it turns out

Running at 185* is not a problem. No way you should run that hot with salt water in the engine. Even though I run strickly in salt water, my engine runs 180*. I can get away with it because I run closed cooling.
