the rule is based on who made the gasket not car maker.
some pro gaskets are already, coated, ready to use
others are just plain paper.
I use , Permatex very old school 2B, and , never RTV , in fa ct getting RTV inside any engine is a horror to the max.
but on the intake side , not so much so after all it gets sucked on burned and blown out the exhaust where the CAT must deal with hit.
on the wet side, oil side
getting RTV inside any engine is super and will add up , and land 3 places where you never want it. (not withstanding the RTV glued on oil pan day one at suzuki, under tight QA controls)
1: the crank/rod bearing , oil slots, pack with RTV dust and the bearing seizes. (in that very tiny spot , )
2: the oil pickup screen, may catch some but not the most dangerous kinds. (tiny) nor do you want it in the screen itself... (obvious)
3: the last place is even as bad as #1 the head orifice, .040" device, if it packs up boom kiss off head and cam bearings.
but intakes, use any thing but RTV.
I like these (they bought the org. maker, and is super good stuff)

rated for air cooled engines too, and is safe.

but in your cases intake only , most sealants are ok and safe,
Use RTV only when , nothing else can work (oil pan only)
good luck !!!
