Tony,
I do not quite agree with you: The nameplate shall reflect the CODE required PWHT, where the MDR shall list also the HT condition of the formed head, etc. You can have a smless head normalized after forming (due to fiber elongation), welded (w/o PWHT) to the rest of the vessel. In this case the MDR should clearly say what was done, but I would not insist on a PHT marking.
Any comments?

Code UG-116 clearly indicated that both HT and PHT were used for completed vessel, that means not for a part. Head is just a part of a vessel. The MDR must match the Nameplate,
If you are right, let's think this way: When a vessel has more parts experienced HT, which part you will report or report them all?
