Hi all, still chasing air leaks and decided to bite the bullet and remove the inlet manifold, what are the smaller ports below the main ports for?

Found a couple of hoses that seemed ok but fell apart when touched - hope that was the problem. New CCV and hose set ordered. Also gave me the opportunity to remove both purge valve and secondary air pump valve (and blanked off).
