Default Re: High compression head vs cooling

My experience mirrors Old31's. The Berg's a terrific radiator. My truck runs so cool I can't really make an observation for the 6.1 head other than it feels like 60hp, not 40. I suppose a light truck has something to do with that. I'm elated with my truck now.
