You shouldn't need gasket sealer with a new gasket and everything clean before refitting.

you apply gasket sealer to the cut out sections only.

each side there are "u" shaped cutouts. these have sealent in them.

its all in the service maunal in the downloads section

Are you sure? There are no U shaped cutouts on the NC35, I assume they NC30 is the same? (been a while since I set eyes on a 30 engine. The U's are usually found on the straight fours, etc.

Edit - I stand corrected, the manual does indeed recommend A-bond. Still no u-shaped cutouts though.
