Default exhaust manifolds

Is it normal for gill big block manifolds to have water sitting in the bottom of the manifolds after you shut off the motors?

As in the water jackets, (yes) or as in the exhaust ports (no)?

the water was in the exhaust ports.
two cylinders to be exact.
so there has to be a water leak somewhere in the manifolds or riser pipes correct?

Same manifold? Any water trails? Might do a pressure check.

Either there is a crack in the manifold or you are getting water reverting back up ( this is called reversion) usually at idle in the exhaust stream were the exhaust gas meets the water outlet flow. Also make sure you are not idling to low of rpm's.

There is suposed to be a thin piece of stainless steel between the manifold and the riser, I can't remember the name of it. It stops condensasion from the inside of the riser from running down into the manifold.
Make sure that has not been removed.

Turbulators are designed to keep any condensation or moisture from entering the manifold during the cool down process.
