I know that this thread is really old.... But being that I too was also just searching for info on the Ford Motorsports SVO "Victor" heads I figured that I would post up the part number since you guys were wondering. Plus it will help any future Yellowbullet/google searchers.
Ford Motorsports part Number for these heads is: M-6049-V351
Hopefully this will help someone else in their search on these heads. These heads are identical to the original Edelbrock Victor #7721 race head only with a Ford part number for use in NHRA. This was the staple head in NMRA Hot Street prior to the Victor Glidden cylinder heads
