[squid-users] deleting headers

Is it a bad idea to put this in the conf?

forwarded_for delete
header_access From deny all
header_access Referer deny all
header_access Server deny all
header_access User-Agent deny all
header_access WWW-Authenticate deny all
header_access Link deny all

I accessed a "What's my IP" site and it knew that I was using a proxy, it even said squid 2.6.
I beleive some sites will block me base don the headers but won;t some sites block if headers do not exist?
