Yes, lash always grows when hot....

Response to Valve lash

On an iron block/aluminum head engine, I see .006" growth in lash when hot. On an all-aluminum engine, I see about .015" growth when hot.

And to be honest, with all the factory stuff I've done (cast iron/cast iron), I've never seen lash close up when hot. It always stays the same as it was when I set it cold, or it will open a thou or so.
