Retourqe head /valve adjustment

Re-torque when still hot. I had to do this with a head gasket once, after 1000 mi as I recall. Many today are "perma-torque" (trademark), but still wouldn't hurt (if a bolt doesn't snap) and easy to do on a slant. My V-8's require removing the exhaust manifold to get at all the bolts. I can't imagine that torquing will affect the valve lash at all.
