You probably need to figure out who made the crank and ask them. Looks like it was probably designed as a blower crank and was machined different than stock. Very possible that whoever machined it got the key in the wrong place. Other option is that your cam has 6 degrees of advance machined in. Doesn't seem like a big deal to me, I'd run the cam at 106 anyway or maybe back it off a couple of degrees and run it at 108. Since you have some questions on stuff you might go ahead and double check the cam timing on #6 hole while you are at it. If #6 is the same as #1 then you should be good to go.
