Mmmmm......dont think you'll get all the swarf out with compressed air, if that was me I would take the head off, ok your going to need a new £30 head gasket but if you fit the helicoil yourself its a cheaper fix than using a garage, only takes a small amount of swarf to damage the bore......
One, is never going to be enough.....
