Cylinder Head G15 R16
Datsun Roadster Silicon Bronze Valve Guides - Set of 8 or In 4 packs of Intake or Exhaust
R16 Silicon Bronze Valve Guides (8)
In photo Intake on top/exhaust below. Nissan guides were mediocre brass and standard on the OD not providing adequate press for re-installation. Proper guide press fit is essential in rebuilds. Losing a guide in older engines is more common depending on how many rebuilds have been performed. These guides are slightly oversize on the OD to provide the correct press fit.
