Common problems.head bolts loosing their strength,crack in the head or in the seat,look of rust marks and have it maged.Warpege in the block or head,nitrous use,if you use it.Heads could be ported to the max and a crack in the port.Mrmopartech
New headbolts, freshly decked heads and block, new head gaskets, no nitrous ever, and mildly ported heads. I either have a cracked head or block, either way it sucks this late in the season. Time to upgrade.
