Default BMW OEM cam specs

I had a lot of trouble finding reference for BMW OEM cam specs. I spent a number of hours researching and figured I'd compile the data into a table. Hopefully this will be useful to more people out there:

Just unformatted text:

M50B20nv // int: 240º(9.7mm) // open:24º close:36º // exh: 228º(8.8mm) // open:38º close:10º
M50B25nv // int: 240º(9.7mm) // open:19º close:41º // exh: 228º(8.8mm) // open:35º close:13º
M50B20tu // int: 228º(9.0mm) // open:3º close:39º // exh: 228º (9.0mm) // open:39º close:9º
M50B25tu // int: 228º(9.0mm) // open:4º close:44º // exh: 228º(9.0mm) // open:35º close:13º
S50B30 // int: 260º(12.0mm) // // exh: 260º(12.0mm)
S50B30US // int: 252º(10.2mm) // // exh: 244º(9.5mm)
S50B32 // int: 256º(9.7mm) // // exh: 240º(9.0mm)
M52B20 // int: 228º(9.0mm) // open:4º close:44º // exh: 228º(9.0mm) // open:39º close:9º
M52B25 // int: 228º(9.0mm) // open:4º close:44º // exh: 228º(9.0mm) // open:39º close:9º
M52B28 // int: 230º(9.0mm) // open:1º close:49º // exh: 228º(9.0mm) // open:39º close:9º
S52 // int: 252º(10.2mm) // // exh: 244º(10.2mm)
M52B20tu // int: 228º(9.0mm) // open:-6º close:54º // exh: 244º(9.0mm) // open:47º close:17º
M52B25tu // int: 228º(9.0mm) // open:-6º close:54º // exh: 244º(9.0mm) // open:47º close:17º
M52B28tu // int: 228º(9.0mm) // open:-6º close:54º // exh: 244º(9.0mm) // open:47º close:17º
M54b25 // int: 228º(9.0mm) // // exh: 244º(9.0mm)
M54b30 // int: 240º(9.7mm) // // exh: 244º(9.0mm)
M54b30ZHP // int: 248º(9.7mm) // // exh: 248º(9.7mm)

Here's a couple versions in .txt and .doc; I hope you find this info valuable. Please let me know if you have verifiable data that differs from this. This data is only as good as I've been able to collect online so far. Thanks in advance for your contribution to this too! Thanks TIem!
