SBC 350 crate engine valve adjustment

[dwstrick55]

Hi, I have a SBC 350 crate engine 10243880 with Vortec heads 12558062 and would like to know the correct valve lash. Has the factory roller cam and lifters.
Thanks, Dave

The valve lash is zero, the lifters are self adjusting hydraulic so it's set it (proper preload) and forget it.

The crate engine should come with valve lash preset.
