My first set of TF heads showed up today and I figured out a couple of things. First of all they need 10x of the longer 5.000 inch head studs. That is a common part number but until TF or ARP build a kit you'll have to source your own. Same stud that is used in the B1 kit so if you have a spare B1 head stud kit laying around you can rob them from it. If you're building your own head stud kit I'd order 24 of the 2.725 short stud from ARP. The 2.725 stud fits better than the standard 2.750 stud that they use in their kits. The 2.725 stud screws in further and clears the header flange.

Even more interesting is the fact that the rocker shaft studs need to be all short ones. No long ones required. I used 10x of the 2.500 ARP stud and it worked just fine.
