The Purpose Of 1.6 Rockers

Aside from the slight increase in lift and duration at .050, compared to stock stamped rockers most aftermarket 1.6 rockers would give you:

1. more precise and consistent ratio (machined vs. stamped)
2. a rollerized tip to reduce friction and side loading on the valve tip
3. lighter weight for higher rev capability (debatable depending on design)
4. adjustability

Plus they look cool. :headbang:
