I see on the forum that plenum gasket leakage can be a problem with the magnum engines. Is there any test for plenum leakage that a owner could do? I don't have any spark knock but the engine just feels like there is a vacuum leak.

The easiest test is to open the throttly body blades and look down the bores with a flashlight. If you see more than a film of oil your plenum gasket is gone.
The other test is:
1. Allow the engine to reach operating temperature, then shut it down.
2. Disconnect the breather hose from the air cleaner and attach a vacuum/pressure gauge to the end of the hose.
3. Remove the PCV hose from the manifold vacuum port and PCV valve and cap both the port and valve.
4. Restart the engine and allow it to run for several minutes to stabilize the crankcase pressure.
5. Watch the vacuum/pressure gauge - Slight pressure is OK, vacuum indicates that the intake plenum is leaking and allowing the engine to draw a vacuum in the crankcase.
