I ve done quite a bit of searchin' and your right there doesn't seem to be a cross reference to the Accel plugs.
They are HEADER plugs for small or tight spaces around the header and designed to remove the heat from the combustion chamber quickly.
I had the same plugs in my 383 but with 906 heads, they worked great, but i now run the Champion rj12yc plugs because it was hard to get the Accel plugs.
You can however get them from www.carshopinc.com
or for 75 440 engines
Bosch HR6BC
AC DELCO R43S
NGK BPR5EGP or V POWER XR5, OR IRIDIUM XR51X
CHAMPION RJ12 YC or for tuning specials J63 or J65
hope that helps a little.
