Premium Grade Head Stud Kit for 996TT
Head bolt stretching is the major cause of blown head gaskets and head gasket seepage. OEM head studs are fine for mildly modified 996TT's up to 700 HP. Beyond this power level, we recommend and install in all of our built engines a better head stud and hardware. Our head studs are made from a premium grade 8740 alloy that is rated far superior to "aircraft grade". They are heat treated to 200,000 PSI. This insures an unbeatable material yielding a tensile strength of 250,000-280,000 PSI for unmatched clamping force. We have installed these studs with great success in over 25 996TT engines that we assembled in 2005. This is a must for any 996TT engine build and requires no modifications to install these in place of the OEM fasteners.
