I installed a 3 bushing and now my readings are:

IO 9 BTDC
IC 39 ABDC
EO 49 BBDC
EC 1 BTDC

I am within 1 of the cam card, I think I will leave it as is.

It's fine like you now have it IMO.

Two keys? Maybe for a blower hub. He's talking about changing the phasing of the cam. Cutting a new keyway does not need to be done for a simple cam timing change.
