Intake Leak Fix ?

Been chasing an oil leak on the Demon. It only leaks when it's running and under pressure. Pulled the distributor to check the o-ring and it looks okay, so poked around with a small screwdriver between the intake and the block and there's about an 1/8" gap where the screwdriver pokes thru.

Wondering if this small gap can be sealed without pulling the intake again?
