So I set the lash cold and subtracted. 006 from the specs as it is an iron block and aluminum heads. .010 I and .012 E. Was fine cold. Ran the car hot yesterday to verify no valve cover leaks and had to pull 1 cover. Hot lash check ....way too tight. I almost feel like I needed to add .006. What's everyone doing? I'm going to set the cold lash to .016 and .018 or should I go more? Spec is .016/.018.
