KCF-182Y have a 6.70mm 'post' thickness designed specifically for 182-SF and 182-SG camshafts. Set of 24 buckets. Kelford Cams DLC Coated Buckets: Larger internal fillet and reinforced skirt. Increased rigidity increases both camshaft and bucket longevity. DLC coated follower surface decrease friction. Decreases surface wear and oil temps. Improves torque required to turn the camshaft. Note: There is a fixed internal length for each part number. Setting valve clearance (Lash) is required by adjusting valve tip heights, seat cut depth and camshaft base circle size.specifically
