Magnum R/T heads - do they Have wet corner exhaust manifold/header Bolt holes???

Hello. I have a set of magnum r/t heads on my 402 and may have to service the steering box which means loosening the header - don’t potentially want a pile of antifreeze everywhere so I’d like to know if the magnum R/T heads have wet corner bolts like the regular LA heads?

if They do, what is the preferred thread sealant to stop weeping on re-install?
