Cold Valve Lash Question

tubbedamx said
I have a question about setting cold valve lash and I think I’m overthinking it.

Working on an 408, iron block, iron heads, solid roller with iron crane adjustable rockers.

Cam card calls for .008 hot. I’ve been reading lash increases with heat and an all iron motor will increase .002-.003. I have it in my head the lash will tighten up with heat.

Thanks
