Just noticed some rust between my exhaust manifold and riser on my fresh water cooled 454 crusaders going to change risers and gaskets if its leaking out it might be ready to start leaking in we don't want that not to say it can rust the surface of the manifold that will make for a bad seal. Any other thoughts on this engines run cool 180 but I don't know how old they are so best to change them.
