I posted this in the tech forum but perhaps it's more appropriate here?

I have the following and have not been able to track down the exacts based on the casting numbers, I have tried all of the normal reference guides, ie., Waynes Engine Book, THE Parts and Tech Catalog, the Porsche Tech Spec Books, to no avail.

The Cam Towers 901.105.111.1R are the same towers in all of Waynes Engine book pictures yet it is not listed in the parts section. The rest are:

901.105.111.1R: Cam tower from a 77 I think.
930.105.148.7R: Cam for an early 3.0?
930.105.147.7R: Ditto?
930.105.101.0R: Timing Chain Cover or Housing?
930.105.102.0R: Ditto?
930.105.105.0R: Timing Chain Cover or Housing?
930.105.105.0R: Ditto?
930.104.329.2R: Heads from what???

I really need help here guys...
