Actually Richard was right. It's 8 not nine mounting holes on the drivers' side of the L6 head.
The holes are bored at 3/8'' -16 UNC. I use a stud overall about 2" long, threaded 3/8-16 UNC on the head side [about one- to 3/4'' deep] and finer threaded on the manifold end: 3/8-24. The fine threads don't come off as easily and give better adjustment fitting up. I don't remember where I got the studs-- my machinist may have come up with them. They are very similar [if not identical] to some Carb studs.
I have a mixed bag of some bolts and some studs, but if I were starting over. I'd go all studs. Much easier to hang the headers and intake when setting up.
Good Luck.
