Does use studs on their 12 valve head with a steed? If so who's studs, what part numbers, etc. Hopefully ARP has something.
 
I used the same studs for the turbo on my head from cummins. They're 3/8-16 thread. Fastenal would be cheaper I think I paid like 5-6 bucks a stud from cummins. Packing is expensive!! Lol
 
I'm going to be getting a set for mine from a local bolt warehouse, last time I got a set from them I think bolts and nuts was $35. Those are standard strength tool steel though, nothing special but I am not running crazy boost numbers.
 
Don't forget to grab new spacers too. The cummins one's will run you another ~$120 ;-)
 
I'm guessing one side is 10X1.25 and the other is 10X1.5? You just have to make sure the side with 10X1.5 is long enough.

Edit: ARP doesn't even know. The guy I spoke with said they retail for $239 and he thinks the 10X1.5 end is 1/2." It is one side each pitch and the 10X1.25 comes with the nuts and washers.

I use 40mm steel hex cap screws. Threads are M10x1.5

At 40mm they run almost flush to the back side of a stock 12v exhaust flange.
 
I used stainless socket head cap screws from Fastenal. I bought a few extra for spares and stainless lock washers. Working great and easy to put in and remove.

The threads in the head are 10mm unless you drilled them out and put in inserts for 3/8".

Make sure you use spacers with whatever fastener you use. It'll help prevent them from overstretching vs. short ones without spacers.
