S50-B32 Cylinder Head

[siemi]

Hello,
I was wondering if someone could point me in the direction of a reputable source of BMW engine components in the UK, specifically a S50-B32 Cylinder Head. I have checked ebay and there is one available, but wanted to know if there are further sources that any of you have had good experiences with.
Thanks in advance.

I've used http://www.fabdirect.com in the past, don't think they were the cheapest but good service and the parts were as described
