    Exactly what I was taught, Never expect any hp gains out of springs/lifters/rockers just be glad you have a more reliable valvetrain.

    The 1.85 rockers adds 5 degrees at the valve when comparing it to a 1.7 rocker and bumps the lift to .514".
    The downside is finding cam lobes to work with the high ratio rocker for a dod street application. Alot of LS cams are high .500's, low .600's on the lift and designed around a 1.7 rocker. A .600" lift cam turns into .653" which isn't real street friendly on springs with the short duration. Luckily Lunati have some new lobes that will work for me.
