Hi and thanks for the replies.

There is no intake manifold installed, just a Torque Plate and a 1104 FelPro gasket. The block was pressurized with the AR engineering tool, no leaks on Bank 1 with 20 psi with the head. On Bank 2, there is a leak with less than 10 psi applied,
with the cylinder head or torque plate on, Felpro or Cometic Gasket and sealant around the coolant holes.
