On a cast iron hemi with aluminum heads I set the valve lash at -7 to be correct when it is hot. What do I set it at cold with a Keith Black aluminum block and aluminum heads? Thanks for youir help.

I used the suggestions from Crane to start out with -.012 and check it again when the motor got up to operating temps., that worked well That was with a KB street Hemi aluminum block and aluminum Dart water heads.Start with -.12 and see how it works for you and let us know
