Head bolt stretching is the major cause of blown head gaskets and head gasket seepage. Evolution Motorsports Head Stud Kits 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. This is a must for any 996TT engine build and requires no modifications to install these in place of the OEM fasteners.
