Got a friend with a 06 cummins with a built motor and twins. It cracked a head so he put a new o-ringed cummins head on and ever since it keeps blowing the head gasket and pouring oil out the front of the head. Got it together last night and it made it about 5 miles and the same thing happened for the 3rd time. Arp 625 studs, block and head checked by a machine shop, .010 protrusion on the o-rings, composite gasket with drilled steam holes. The head was checked by 2 different machinists and the block was checked by a mobile machinist. Anyone got any recommendations?
