ASF42C
Is the CLV head (335-385 Series) 14mm plug. Same as old AF 42 but with suppression (S) and copper-core (C)
BF82
These are the old Y-BLOCK and later straight six plugs
NGK- I cannot speak Japanese other than HONDA and RODAN.

I did a google search for a cross reference. NGK AR6FS crosses a bunch including AC delco, denso, champion. Says it's the same as Champion RF 18C NAPA X571 Autolite 33.
