What is the roller rocker formula?

Or how do you figure lift going from 1.5 to 1.6 roller rockers? And this time I'll write it down! Thanks.

you'll get roughly about .030 more lift going with a 1.6 rocker

Since the rocker ratio is multiplied by the lobe lift to get valve lift.. you just divide by 1.5 with the normal valve lift and then multiply by 1.6. So .400 lift /1.5*1.6=.427
