SPECIFICATIONS Brian Crower Valve Keepers & Locks. Buy now and get same day shipping! Note: If running a late model cylinder head (after 2004), you may need to purchase BC2940 keepers to accommodate the BC2010 or BC2011 retainers. Honda changed the keeper groove angles, therefore your stock keepers/locks may not fit the BC retainers properly causing potential damage.
