Need help on centerlining my cam.

OK, I did TDC, mounted the dial indicator and everything. I rotated the engine till I got to .050 before maximum lift and got 61 degrees. I continued rotating until I got to .050 after maximum lift which was 149 degrees. Add those together and divide by 2 = 105 degrees. My cam card says my centerline is 106 degrees. So if I understand correctly, I need to advance the cam 1 degree? Please tell me I did this right. :p And how do I advance the cam 1 degree? Do I need to order an offset key for one degree?

Thanks
