Knackered thread for Supercharger oil feed

[dabigginger]

I tightened the oil feed for my supercharger oil feed at the end where it meets the cylinder head. I over-tightened it a bit and it has knackered the thread on the cylinder head and it leaks A LOT of oil, and I cannot drive the car like this.

Can I repair this with a heli-coil, or is there a better way to do this?

Any help or advice would be appreciated.
