That is part of the intake manifold end plate / bypass . I broke mine when i dropped my intake manifold almost exactly the same section. I put it back together and drove it for 1k miles no issue at all even under boost. I did end up replacing it though as an excuse to get the dual pass endplate from zzp. If you dont wnat to spend the money for upgrade i definitely keep driving it.
99% certain it won't matter,it's not a surface the gasket seals against. It does nothing but hold the gasket ring in place and it's the low pressure bypass port ot the LIM/IC. Slap it back together with a little dialectric on the gasket ring.
