This is a brand new (not rebuilt) BMW head for E28 535i. It's a euro head, with 264 degree cams. Casting date on the head is 1993, and the price includes a new head gasket and new head bolts. $1300. Not cheap, but for someone who only wants to do this job perfectly, it should be worth it. BTW, Chris Graff, the M535i list guru, has seen the head and can verify its authenticity.
