In which case George is probably gonna tell you that you don't need an offset key.

I put a 0 marked key in it and ran it. It ran good but I've never ran it with a stock key. Maybe I should take it out see how it runs.

Stock engines tend to perform best with the stock key. At most I would only advance it 10 degrees but like I have said a stcok key will probably be your best bet with a stock cam. Thats been my experiances
