I use the 2.725 long studs since they are shorter and will clear the header flange. I told Trick Flow that but they went with the longer studs in their kit. I also told ARP about it but they sell the longer studs in their kits. So whatever......

You can just order the studs by description from ARP. I think they have a website now with a shopping cart but you'll have to check. I also order ARP stuff from Summit sometimes but Summit doesn't have everything in their catalog.
