Narrative:

[We were switched to] tower as we were approaching the hold short line for runway 24L. Tower asked if we were ready to depart. I answered that we were ready for departure. Lax tower cleared us to RNAV to casta cleared to takeoff runway 24L. I informed the controller that we had the gorman four departure loaded. He said that since we already had that departure programmed to go ahead and depart on the gorman four departure fly heading 250 cleared for takeoff. We completed the before takeoff checklist and conducted a normal takeoff from runway 24L. The captain checked in with socal departure who cleared us to climb and maintain 9;000 ft and turn right heading 030 to join the departure. We complied with the instructions and set up an intercept for the gmn 142 radial inbound to gmn. As we began intercepting the gmn 142 radial socal asked us if we were joining the casta two departure. The captain informed him that we had been cleared for the gorman four departure.socal then cleared us to turn right heading 360 and that he showed us as filed for the casta two departure and that we had strayed into another approach sector's airspace. Apparently; the change in departure procedure by the tower controller had not been conveyed to the subsequent controllers. He then had us change to a new departure frequency. We checked in with the new controller on a heading of 360 and level at 9;000 ft. The new controller cleared us direct to gmn and climb to 15;000 ft. We were then given clearance to climb to FL340 and [to proceed direct] ave direct oak. No traffic conflicts or restricted airspace penetration occurred. There were no further incidents during the flight. After the initial confusion and we were climbing to FL340 between ave and oak the captain took a look at our pre departure clearance and discovered I had missed the change on the pre departure clearance to amend the departure to the casta two. On my initial contact with clearance delivery there was no mention of the departure change so my error went unnoticed.

Title: An A330 First Officer failed to note the revised PDC clearance from the filed GORMAN SID to the CASTA for their departure from LAX. When the error was noted as they were about to be cleared for takeoff the Tower cleared them to fly the GORMAN as already programmed on the FMS to avoid delay. The Controller apparently failed to advise the TRACON and confusion and an airspace deviation took place before the error could be resolved.
