I had intended on using P seal from ACS but that idea did not work. The final solution was to use the silicone baffling material with backup strips. Today was spent cutting and fitting these pieces to seal the forward portion of the engine baffling.
For the right side, I ended up securing the silicone on the low pressure side of the baffling using an ovesized backup strip to support it.
All substantial pressure leaks should now be sealed.
