Narrative:

On the porte 5 departure off of 28L in sfo; the normal procedure is to turn to a 330 degree heading at 420 MSL; however; the captain pointed out an fdc NOTAM that stated to fly 014 degrees (runway heading) until 2;000 ft MSL. When we did this; ATC told us to turn left immediately; and that they had no knowledge of the NOTAM. After a discussion with company ATC guys; we realized that it was an alternate climb gradient procedure that was poorly written in the weather packet and confusing.

Title: B737 flight crew notes an FDC NOTAM apparently instructing them to maintain runway heading to 2;000 FT departing Runway 1L at SFO on the PORT 5 departure. ATC advises this is not correct and that the procedure is a revision to the obstacle departure procedure only.
