SOURCE: bolt torque specs
I have used Haynes service manuals for (hate to admit it) many decades and I recommend you check to see if this one:
http://www.amazon.com/Haynes-Toyota-Automotive-Repair-Manual/dp/1563923513
doesn't cover your engine.
I have found darned few 'holes' in their coverage.
Auto parts stores carry these and I suspect that even though sealed, the sales people will not give you too hard of a time if you explain you want to insure you are getting what you need.
Haynes is not the same as it was 20 years ago before they were acquired by Chilton but the price/utility ratio is still pretty good.
Mostly I'm annoyed by the move to cheaper paper (newsprint)that is fussier, picks up dirt, tears more easily than the better paper of yore.

Valve Rocker Arm Bolt 19 N·m + 30° (14 lb ft+ 30°)
A GM dealer shows me another source, which says 32 Nm (24 lb-ft). Not sure which one is right but they screwed up my car.

If the vehicle is fitted with a Rocam engine, the valve clearance is not adjustable, hydraulic lifters.
The camshaft caps are torqued in two stages, first 10Nm and than 90 degrees
