OEM style gaskets never need any goop on them. If you plan on removing a particular gasket many times, use a non setting gasket goo on one side only or simply grease that side of the gasket.
3 bond is great for sealing crankcase halves but that normally is the only place.
RTV (silcon) has no place inside a motor where it can come loose and block an oilway. The only place it is normally used is on exhausts to seal joints. Do not ever use it on say a side cover.
There are exceptions to every rule - even mine, but not a lot.
