Due to a slight mistake, I have two brand new M54 valve covers from FCP Euro that are surplus to requirements. If anyone is keen, hey have a lifetime warranty from FCP Euro, but that applies to me only. I'd be happy to extend it to any buyer in this forum as well. I commit to working as the in-between between buyer and FCP Euro. These are them https://www.fcpeuro.com/products/bmw-valve-cover-e46-e39-genuine-bmw-11121432928 Say $400 each, which is a well below cost.
