The only cast header that came on a 390/330 hp was the short style. The long style was exclusive to the 427, including the high riser, which also required a different z bar. There were tube headers available by companies like Belanger. I have a set that has #3 and #7 cross over to the other side, and #4 and #8 wrap around the frame.
