I would go to local part store ,:naughty: competetion cams makes a roller tip
rocker arm which is not like most aluminum full roller rocker arms. These are great for the street. The 1.6 is the way to go instead of the stock 1.52 .
You will get more lift out of your cam a better sound with the 1.6.:naughty:
