I guess you mean TCP/80. Unlike UDP, spoofing source IP of an open TCP
connection is not that easy: you either need to be able to guess
sequence numbers (and then you cannot see what the host has replied to
you), or you need to control network somewhere on the route from
target to the spoofed IP (probably at LAN or at target's ISP)

It is possible to use tor or anonymous HTTP proxy, but it is not
actually "spoofing".
