max valve lift
im lookin at the summit iron heads and they say max .520 lift
when they state this does it mean just the cam lift or the lift after a 1.5 or 1.6 ratio is added?
i have a .443 lift cam and want to put on 1.6 rockers when i put heads on it
thanks

It means the lift at the valve.
Cam lift is typically quoted at the valve with stock rocker arm lift. If your cam is .443", the lift at the valve with 1.6:1 rockers would be .443/1.5*1.6.
