They are from that era but I don't think they used the "n" shaped plugs in 69 chevy engines.

I know that US Pontiac's switched to the "N" shaped plugs midway through the 71 model year.

huh?
Heat ranges aside, USA-Pontiacs used R45S as the standard plug for 1969 through to 1971. They swapped to the R45TS for 1972
I only ran across these "N" plugs a short while ago, but so far I have only observed ones which would be comparable to the "T" or "TS" plugs.
My June 1993 Delco spark plug catalog does not list a R44N for any 1969 Chevrolet; The closest I can find is a 1968 Chevelle that lists a 44N or 44XLS for the 396 265hp/325hp engines. (My catalog is a USA printing, so not Canadian Poncho's are listed).
I'm going to replace these plugs but I am not going to throw these plugs away.
I showed the old plugs to an engine builder today he was amazed by the quality of the construction of the old plug.
They weigh a lot more than the NKGs
They are gapped a tight .35
What do you think ?
