They have shorter duration and lower valve lift (8.5mm instead of the XE's 9.5)duration 251 instead of the XE's 255.
I think this is right, but please correct me anyone

After comparing different documentation I think this correct:

Motor: XE/LET/Rally
Ventilhubauslaß 9,5/8,5/9
Öffnen Auslaß v. UT 60/ 54/52
Schließen Auslaß n. OT 32/ 28/16

Ventilhubeinlaß 9,5/8,5/10
Öffnen Einlaß v. OT 20/14/17
Schließen Einlaß n. UT 72/68/70

Thanx Frank

But i believe those data's are not from standard cams.
according this data, the XE would have a 272° duration and the LET 262°.

These data you can find in the Opel documentation (from the www.hobbes-motorsport site) about the development of the 16V turbo calibra, the 16V turbo rally LET and the 16V F3 engine by Opel, so....
(Only in one publication (rally LET) the standard LET Auslass-Offnen is wrongly written as 60°v. UT (this is the XE spec) instead of the 54°v. UT (as mentioned in the 16V-turbo Calibra publication.)

Probably the measuring method (at what lift?) is different.
