We rebuild light duty cylinder heads in house. As long as the crack isn’t into the deck surface we machine the crack out when counterboring for oversized hardened seats, no welding necessary. 6.2 and 6.5 headgasket failures are not exactly common unless they are abused or subjected to cylinder...

I wanted to do 37's strictly due to final drive ratio's but I am going to use this truck every now and then as a service truck and it was going to be a little to tall with 37's. The cummins actually fits very well. They are getting a little spendy but I have accumulated a few over the years...

Yes they will pull the rpm's if you hold the pedal down, no they don't seem to enjoy it. Leave them stock and they...
