Most cam lash settings are at operating temp.  Lash can be set at room temp. but the number will vary depending on type block and heads.

example: All aluminum 430CI cold lash will be around .005 lash but at operating temp. it could be .022

to adjust intake lash, rotate engine over till same cylinder exhaust valve is 1/2 open.
