rocker arm ratios

Just an FYI. About 25 years ago I had a1963 VW Beetle. The engine had a big bore kit that increased it from 1200 cc to (IIRC) 1385 cc, and a header. The stock rocker arm ratio was 1 to 1. On later VW models they swtched to a 1.1 to 1 ratio. I bolted a set of the later 1.1 to 1 rockers onto my motor & could definitely feel the difference in the motor.
