Ok, looking at my header sitting in the living room, I see six per side.... = 12 total lol.
25mm is real close to 1". I know people re-use the stock bolts all the time, but I also read of people snapping them off and stripping them. I'd really like to end up with the exact same length of threads in the head.
I might just remove one from the car a take some measurements.

reusing the stock bolts is not a good idea because you would have to put washers to make up the difference in the thickness between the stock exhaust manifolds and the new headers, The 3/8 thick will not work because i tried them.

I noticed that the LSx Stage8 locking bolts are listed as being 8mm-1.25 x 22mm FWIW.
