These rocker shims & guides are located right under the rockers between the valve stem and rocker. On normal Hydraulic Lash System, you can order just one standard size. However for Solid Pivot System, you may need to get different thickness depending the valve and rocker clearances. Each rocker and cam clearance should be measured using an accurate gauge feeler to find the right size for shims and guides. There is a total of 8 shims & 8 guides in the Head.
Note: Price is for EACH Guide. Shims are sold separately. Depending on the size, the Shims/Guides may be from Nissan or Tomei.
