    Valve lash cold/hot

    I have a new to me 582 -- the builder says valve lash is .016 hot. My question is...

    I am changing the lifters= I have a Jesel setup-- so i have to remove the assembly... now when i put it togther i want to lash it somewhat close being cold.. as i cant start it yet ..im waiting on some odds and ends but i would like to have it close.. What should i set the lash at cold if the builder has said 016 hot?

    Thanks In advance

    Question, does it have aluminum or cast iron heads?

    Close is about all your gonna get till you can figure out just how much growth your dealing with.

    I would to set them all on .011 to 010 cold.

    Start it, let it get good & warm, re-set them 'hot' let it cool, check again.
    Make note of the lash 'cold' - then you you can set them 'cold' all the time.



    On my motor, BBC 496 W/ cast iron heads.

    I set all mine @ .022 cold, calls for 28 and 30 hot, never had any issues.

    Mine are .26/.26 @ op. temp. Sorry guys, but you know I am learning too, so here is what I do not get: If metal EXPANDS when hot, why is the lash LESS cold? If metal expands, should you allow for more LESS lash when cold? I don't get that!! Should the heat provide less tolerance in itself? For this confusion/reason, I never set mine cold. Until I understand this, I will not take a chance.
