Special Notes: non-Adjustable
* Harland Sharp original series, pedestal mount, GM LS1/LS6 roller rockers are designed to be a replacement for the factory rocker that fits under the stock valve cover. Simply remove the factory rockers and rocker stands and replace with your new Harland Sharp roller rockers.
* We recommend always checking for head & valve cover clearance and proper lifter preload. We have encountered core shift issues that have interfered with our rockers.
* These non-adjustable rockers are designed to the factory specs. If you change camshafts or machine the heads, you will have to correct your pushrod length. Always check before installing.
