It would appear that in fact you have advanced the camshaft by one tooth of the camshaft sprocket. If the cam sprocket has 40 teeth the crankshaft angle (CA) at which the camshaft is timed has been advanced by 18 degrees. If the cam sprocket has 36 teeth the advance is 20 degrees.
That there is no valve-to-piston interference is testimony to how wimpy those cams are in the first place!
