Many of the popular engine families utilize a positive stop type of rocker arm attachment, which does not allow for any adjustment and consequently there is no consideration for different cam sizes or other modifications to the engine block and heads. For that reason, COMP has designed a kit to convert this setup to a fully adjustable valve train. On the Mark V and VI Big Block Chevrolet engines, replace the screw-in studs with those provided, slip the spacer insert through the rocker arm ball, and adjust with the new adjusting nut. These kits are a simple and inexpensive alternative to give the flexibility of an adjustable valve train.
Complete with our 4514 studs, spacers and adjusting nuts, this kit adapts your late model Big Block Chevrolet engine to an adjustable valvetrain.
Includes part numbers 4514-16 studs, 4514SP-16 spacers and 1401N-16 rocker nuts
