Sounds like you have done your homework. When some one mentioned 185 degree temps earlier in this thread I was worried, those temps would destroy a 575 rather quickly.

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

I was running 185 on a N/A 540 with afr heads. It probably would hold 150 F. I wanted temp.

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.
