Quoting Jim Hand on 6/15/2000:
"As the cam rotates at half speed from the crank, one degree change at the cam equals two degrees at the crank. Accordingly, a one degree change in location of the cam will shift the lobe center two degrees at the crank. So a two degree cam key will change the cam timing by four degrees!" End quote.

The discontinued Mopar offset keys contained a set of 5 color coded keys. The natural metal key is 1 degree, which would give you the 2 degree advance that you're looking for. I'm not aware of anyone else making a 1 degree key
