Engnbldr.com he has everything you need to rebuild, including a new head (loaded or bare), and cams.

As far as cams, personally I am aiming for one of his 268C Torkers, good low to mid range.

You can even get a performance head with oversized valves and some other goodies in there, would likely make a good match for any of his cams.

You might scan ebay (search toyota epn) to find some of his goodies.
