We recommend having these cams heat treated after grinding due to the wear problems these cams are known for. Additionally, we recommend you sending us your old lifters for radius grinding since they are made of a very soft chilled iron and are almost always worn out. Heavy duty valve springs are required on the 7008-10 grind and on up. 1500, 1600, 1622, 1800 CC ENGINES ROCKER ARM RATIO= 1.45:1 (AVG.)
