    Default Need advice on lash setting

    I have a 454 with a solid roller cam of unknown make (engine is assembled and installed), 990 heads, iron block, with 1.7 rockers valve lift at .600". This creates a bit of an issue determining what to set the lash at since I've seen anywhere from .014/.016" for tight lash cams to .028/.030' from Comp Cams. Is there a reasonable "middle of the road" lash setting I can use to fire this? I've heard that .016/.018" is where there will the least chance of having issues.
    Anyone have recommendations on what to look for after firing it to either increase or decrease lash?

    Start at .016/.018 and you'll be fine.
