I have a 1972 Mach1 with a 351cj. Last night I pulled the intake and found where water had been getting into the #8 cylinder but from where? The valley pan and intake port is all rusty\crusty at #8. The top of the intake manifold was rusty too. The PO did rebuild the motor and it was barely driven after the rebuild. The car sat untouched out in the weather. It looks like water sat on the intake for a long time. #8 was fouling plugs so is it a head gasket or was water getting into the intake somehow through "seepage"??? I am going to run a compression check before I pull the head but I am also at a cross roads as to what to do next. Do I:

1. remove the head and swap head gasket if compression check fails.
2. remove both heads have then checked, hot tanked and machined for screw in studs and guide plates.
3. Install the roller cam I have.
4. Pull the motor and go through it and clean and paint engine bay a motor.
5. Pull the motor and completely tear it down even though it was rebuilt before I bought it and the intake valley really proves that as spotlessly clean it is.

Thanks!
Wade

Dry intake on a Cleveland, so if you're getting water in a cylinder, it's either because water has entered from outside, you have a blown head gasket, or a cracked cylinder.
