If that foam is crumbling, oil soaked, or otherwise deteriorating, tear it all out.
It will break up and get sucked into the carburetor and the motor will run wrong. Depending on the version of the manifold on your motor, it could be easy, or HARD to clean out the manifold. Best to avoid it all together!
The foam serves a purpose to make the motor quieter. Other than that, nothing else I can think of.
