That's right, there's more than one name in the head and main stud business! Pacific Performance Engineering, also known as PPE, delivers you head and main stud kits built from 8740 chromoly tested to withstand 231,900 psi tensile strength. If you're running more than 45 psi of boost in your Cummins, Duramax, or Powertsroke, its highly recommended that you ditch the stock style head bolts that are known to stretch and replace with a set of head studs. That is, unless you enjoy pulling your head(s) and replacing head gaskets!
