For the rocker shaft stud kit use Trick Flow Part number 61600613 or you can piece it together with ARP individual studs AJ2500-1B and ARP nuts 300-8332 which is a 10 nut package.
The TF kit wasnt out when I ordered my stuff. Not sure the price difference but I know after my phone call 440Source is planning on selling a corrected kit for the TFs.
