does anyone have the resources to cross reference the spark plugs i have below.

champion:

N-62-R (side-gap)

N-60-Y (extended tip)

these are to be for a bbc. i would like to see what they would be equivalent to. weather its autolite or any other name brand plug.

i'm not sure even if these plugs are still sold under these numbers.
