Huh? If you degree it with a timing chain, you can't pull the chain off and switch to the gear drive and expect the setting to hold. The whole point of degreeing is to establish a known reference between the cam and crankshaft. The top sprocket of the timing chain allows you to adjust the rotation of the cam a few degrees either direction. Your gear drive should allow the same adjustment, but you would have to through the degreeing process all over again.
Personally, I think you should set that gear drive on a shelf somewhere and forget about it. A good double roller timing chain is all you need. :thumrigh:
