This kit is required to install our street performer camshafts for the 5VZ V-6. The complete set is available to make your cylinder heads accept our cams without causing problems. This kit converts your heads from a shim-over bucket to shim-under buckets.
This is to allow more surface area for the cam lobes to ride on the buckets. The stock buckets are barely big enough for the stock cams! Along with the shim-under buckets, a set of Chromoly retainers is included to allow the pocket for the under-bucket shims to sit. Valve springs, keepers, and seals are also included.
