years but one might be the tendency for tappet guides to work their way out of the cylinder head and hit the cam shafts this is noisy and very expensive we can t solve the problem but our tappet guide hold-down kit certainly prevents it the kit consist of six metal plates plus bolts that are bolted to the cylinder head grooves in each plate overlap the tappet guides holding them firmly in place simple and effective prevention we fit this kit to virtually every cylinder head rebuilt in our shop installation is simple and requires a drill and a 10-24 tap and can be done with the head and cams
