Default How to increase lift without cam change?
Putting in new valve springs and considering whether I can add a little lift. How is this done? I currently have a 226 .553 114 cam.

The only way is to replace the rockers with a higher ratio.

what kind of grind do you have now? higher ration rockers arent really made to work with aggressive ramp rates. with 1.8 rockers your looking at about .585 lift. i say you keep the stock rockers and get a new cam. be cheaper anyway.

Can I go with even larger rockers for more lift?

After the price for a decent set of 1.8 ration rockers, you just bought yourself a new cam. Like jrp said, you need to ask lunati if they recommend 1.8 rockers with their cams. I know its not recommend for most cams due to agressive ramp rates.
