What's an "'orrible noise". I consider mine to make an awful noise when the chain is all gritty and at this time of year even with my new cog, chainring and chain it takes about 150-200 miles to sound grim to me.
If it's a track hub I'd be careful spacing out the cog I wouldn't go more than 2-3 mm as you need to make sure there are enough threads of the cog engaged with the hub. I'm not sure why you would need to redish the wheel.
