Please describe your method of Google spoofing. Currently, I know only two methods to avoid Google tracking completely: pool all requests though a proxy/third-party service or bombard Google with randomized queries. Second method has huge disadvantage as Google quickly catches up and start asking confirmations that you are not a machine.
Also, in any case, you will not be able to keep settings for google services like adult filters on/off in Google Images or subscription to news blocks in Google News. And, of cause, you will not be able to be logged in in GMail or Google Docs.
