Narrative:

On taxi out to depart on runway 28L; our SID was changed from the san francisco eight to the quiet two departure red bluff transition. We quickly briefed the SID and the first officer made the takeoff followed by an immediate turn to 030 degrees. As we passed through the 350 degree radial from sfo VOR departure told us to turn left to 320 degrees for 'noise abatement.' I think he realized we had missed the turn to intercept the 342 degree radial and was doing us a big favor. I immediately looked at the SID plate and noticed that the 030 degree heading was to intercept the 342 degree radial and not for radar vectors on course. In retrospect we should have taken more time to familiarize ourselves with the departure. We also should have realized that with the VOR on the aircraft; the immediate turn to 030 degrees would have us crossing the 350 degree radial almost immediately.

Title: B737 FLT CREW HAS A TRACK AND HDG DEV DURING DEP FROM SFO.

Narrative: ON TAXI OUT TO DEPART ON RWY 28L; OUR SID WAS CHANGED FROM THE SAN FRANCISCO EIGHT TO THE QUIET TWO DEP RED BLUFF TRANSITION. WE QUICKLY BRIEFED THE SID AND THE FO MADE THE TKOF FOLLOWED BY AN IMMEDIATE TURN TO 030 DEGS. AS WE PASSED THROUGH THE 350 DEG RADIAL FROM SFO VOR DEP TOLD US TO TURN L TO 320 DEGS FOR 'NOISE ABATEMENT.' I THINK HE REALIZED WE HAD MISSED THE TURN TO INTERCEPT THE 342 DEG RADIAL AND WAS DOING US A BIG FAVOR. I IMMEDIATELY LOOKED AT THE SID PLATE AND NOTICED THAT THE 030 DEG HDG WAS TO INTERCEPT THE 342 DEG RADIAL AND NOT FOR RADAR VECTORS ON COURSE. IN RETROSPECT WE SHOULD HAVE TAKEN MORE TIME TO FAMILIARIZE OURSELVES WITH THE DEP. WE ALSO SHOULD HAVE REALIZED THAT WITH THE VOR ON THE ACFT; THE IMMEDIATE TURN TO 030 DEGS WOULD HAVE US XING THE 350 DEG RADIAL ALMOST IMMEDIATELY.
