Anyone ever go faster after switching from 1.6 intake rockers to 1.5? I’m thinking velocity increase with less lift. Which is better, velocity or volume on intake flow?
Waht andy said, and I would add that you need to make sure you are still controlling the valve, if you add lift with a higher rocker ratio and lose control of the valve you will probably lose power.
If your talking SB I would always run the highest rocker ratio I can find to bring the pushrod up straighter (I know it's not much but it don't hurt) then match my cam to those rockers to get the valve action I want.
I am not causing global warming, I am just trying to hold off a impending Ice Age!
