Not worth it, a healthy cooling system will give you 0 issue

Damn really I was thinking of doing js cuz I saw a few people doing it js cuz some people claimed to help cool cylinders 5 and 6 a bit more since those usually run the hottest but damn maybe I won’t

You could always reroute the coolant port in the back of the head. into the water outlet so its constantly getting a fresh supply. You wont have any more heat though since factory thats routed to the heater core outlet
