Just lashed my valves on the 511 with victor heads. First time since last august when i lashed them cold at .016" for the engine/cam breakin. Spec hot is .020" on both int and ex. I relashed them hot at 180* doing one side at a time then reheat for other side. Only had to relash 4 valves on driver side and they really didnt need it. just trying to get them all exactly the same. 2 valves on pass side. All very much the same at .020", but 1 was a little tighter than i like. The HS rockers held the lash good and the flat tappet broke in well from what i see.
