I think unless you have problems with it not running smooth try to run leaner.
You are doing what I plan on doing with an LSx at some point. I want to lean burn one, with inconell exhaust valves (not to mention a ton more mods) and stay leaner than about 17:1 for eco cruise.
No sign of excess heat. The crazy injectors I have now accelerate smoothly and crisply (light load but quick enough to keep up with traffic) at 16:1 and 32-38 timing, but will only hold smooth cruise at around 14.7-15.4 and 26-32 timing - crazy. Trailing throttle is 14.7 when it could be 22+ on some engines.

New injectors will fix this, and over heating valves should equate to higher than normal coolant temps over time, so I will watch for that, but no issues so far. I'm tossing between the new EV14 Bosch 52lbers and a more expensive set of 725cc Injector Dynamics. Both are very accurate right down to very small pulse widths and offer state of art atomization.
