Anyone know the max recommended lift for OEM LS7 Rockers?

Thanks!

From what I have heard the range is like 640 to 660 lift.

We have run upwards of .685" lift on OEM rocker arms and trunions. That being said, it really depends more on your lifter/spring combo as to what lift the valvetrain can handle. If we can assist with any camshafts or valvetrain components please let me know and I'll be happy to help!

These are CHE rockers (OEM with their bushings). I called CHE on Wednesday and they said right abound .650"....above that and 'all bets are off'.

Default Che ls-7

Hi All, I too agree with the CHE tech AND the use a Lash Cap on each valve would help.
I also fit their Rocker Arm Studs.
