Harland Sharp SB Mopar kits require taller valves. Approximately .100-.150 are necessary for correct geometry but sometime lash caps can be used. Needle bearing allow for more oil flow to the rockers. Oil restrictors may be necessary to maintain oil pressure. Rockers are designed for big lift cams requiring .100 to .150 taller valves. Rocker shafts are drilled to allow for 3/8 mounting hardware. Needle bearings allow for more oil flow to the rockers. Oil restrictors may be necessary to maintain oil pressure. Rockers are designed for big lift cams requiring .100 to .150 taller valves. May require rocker shaft perches to be milled and install offset blocks and stands to correct geometry and allow for more spring clearance. Includes rockers, shafts, and spacers.
