Just did head studs on a 6.0. Had heads checked and just needed to milled. Put the truck together and tried to start it it would just crank. My buddy put started fluid and got it to start. Truck started blowing white smoke out of exhaust. Come to find out the dowl pins needed to be shaved down too. Causing the heads to not sit flush. Water was passing through the gasket. Pulled it apart and found a bent pushrod.
Once again i shaved the dowl pin and put it back together and started it up again. Truck had a slight knock so I took it apart again found another bent push rod. Do you think milling the heads could have cause all this problem?
