Hey to all, new to this site and saw all the head and timing chain related posts. Want to pass on a source for engine parts that I have had excellent luck with. They carry a lot of OEM Japanese stuff, just without the Toyota logo on the box. My experience with these folks has been above and beyond the call. You can do head and chain jobs, or rebuilds with Japanese parts for a fraction of the domestic part prices, and the job will last. Check em out, and hope it helps.

I have also found these guys to be a lifesaver for us up here in Alaska. They are a toyota only wrecking yard and know their stuff.
