Max lift with AFR heads?
...does anyone know the most lift AFR 190 heads can handle (out of the box from AFR)....I'm gonna do a cam swap...thinking about the GM847 or a little bigger and think I might have to swap springs.
Thanks! 350Z

your heads more than likely have come with the 8020 1.450 springs.
1.450" OD Hydraulic Dual Valve Spring, 120 lbs. on seat, .550" maximum lift, AFR #8020
i wouldn't recommend running those springs with an 847.
