Does a head gasket needs any kind of silicone or glue prior installation or just proper torque?

No never. Not if both surfaces are good, clean and true. I've never, ever, used sealant on a head gasket.

If the surfaces are NOT true etc. then you should get them faced by an engineering firm.

Always use a new gasket every time. Never use an old one.

(The only exception is that the vehicle manufacturer says to use sealant in the manual.)
