Unless you know what you are doing, stick with stock.
Lots of back to back testing has shown, running the coolant temp around 180 degrees on Iron heads makes the most power with more spark advance, and a leaner mixture.
Aluminum heads, seem to like it to be around 200f.
If you can regulate the fans to keep the engine (assuming alum heads) around 200f, you can run a little more spark advance, and dial in a slightly lean WOT AFR and make more power. If you care.
