We start by doing what the factory should have done. We replace the standard powdered metal guides with a CHE bronze valve guide THROUGHOUT the head, not just the exhaust side. Our Stage 1 ported GM LS7 is what you NEED for your 06-13 Z06 or 14-15 Z28 (or LS swap).  Need pushrods, cam, intake, lifters, gaskets or anything else LS on the planet?  We’ve got them on the shelf ready to ship!  Contact us now if you have any questions!
