CHrys LM 318 Just rebuilt-1,3,5,7 head overheating

[RacerChris K]

Just had both of my LM 318's rebuilt for my houseboat. Still have one in pieces, but have rebuilt the first one. 1,3,5,7 head on the counter-rotating motor is overheating.Any ideas? I think it's due to a water blockage......

Wrong head gasket, leaking haed gasket, cracked head
