This valve regrind gasket set and head bolts combo pack suits HSV vehicles and similar platforms fitted with a LS1 5.7L V8 engine.

This valve regrind gasket set (VRS) is designed to meet and exceed OEM specifications. Each item of this kit has been checked and evaluated, so you can be assured of quality fitment every time.

The head bolts included in this pack are best suited for standard and mildly modified applications. These are a torque-to-yield (TTY) type bolt which means they can be tightened past their elastic limit, guaranteeing high and uniform clamping forces. Other benefits include pre-applied sealant to the threads eliminating the use of thread locker and no-retorquing is necessary after correct installation procedures have been followed.
