Looks good; I have the same.

I have
DEVICE=sit1
BOOTPROTO=none
ONBOOT=yes
IPV6INIT=yes
IPV6TUNNELIPV4=remote_ipv4_address
IPV6ADDR=my_ip6_address/netmask

Is the IPv4 address in the config above the IP address of the HE endpoint
and _not_ your IP address? (In my case I have 72.52.104.74 for tserv3)
ifconfig sit1 should show something like
sit1 Link encap:IPv6-in-IPv4
inet6 addr: your_ip6/metmask Scope:Global
inet6 addr: fe80::link_addr/64 Scope:Link
UP POINTOPOINT RUNNING NOARP MTU:1480 Metric:1
RX packets:756 errors:0 dropped:0 overruns:0 frame:0

RX bytes:76421 (74.6 KiB) TX bytes:88155 (86.0 KiB)
Also check the output of
ip -6 route | grep -v 'dev lo'
