The engine assembly was designed NOT to use any kind of fiber/paper type gasket. Although many gasket companies, as well as the typical Melling oil pump package, comes with a thin gasket, you are best to simply inspect the mating surfaces (oil pump and block/cap) so to assure flatness and no pitting or metal flash, then only use an anaerobic sealer (cures between metal-to-metal in the absence of air... DO NOT USE RTV silicone which requires air), then tighten to OE specs.

The very last thing you'd want is for some foreign material -- gasket material and/or RTV silicone -- to find its way into the oil pump or passage ways to then restrict the flow of oil.

Remember: RTV silicones are the most widely mis-used and improperly applied chemicals in the engine building industry. RTV should only be used at critical open-gap intersecting corners, such as the four corners of an Intake mfld or oil pan gasket assembly. Avoid spreading RTV all across a pre-made gasket, and never onto a rubber gasket.

I'm a former gasket engineer from a major company, wrote the instructions within their kits, taught hundreds of seminars, and was the lead person on their tech-line.
