well, I can see ur message has been here for quite some time. Most probably you got the answer to ur request.
I just did the valve clearance on the engine of my SJ413 that has the 1000cc engine of an SJ410 :
When cold: 0.13mm Intake and 0.18mm Exhaust
Engine sounded well and worked fine after that.

cylinder bolt torque settings stage 1 15 ft pounds
stage 2 50 ft pounds
stage 3 85 ft pounds
valve clearences 0.15 - 0.20mm inlet
0.22 - 0.27mm exhaust
these are the figures i have been supplied with, you can also use
cylinder bolts stage 1 10 ft pounds
stage 2 50 ft pounds
stage 3 + 90deg.
with my exp, i would use the first guide as the degree method has a tendancy to snap head bolts, especially on older vehicles.

valve clearance is .014 inch for intake and exhaust with engine warm.
head torque it 21 ftlbs, then 44 ftlbs, then loosen all, torque to 89 inchlbs, then to 21ftlbs, then mark and turn the bolts an additional 60 to 65 degrees.
cyl head sub bolts torque 80 to 100 inchlbs.

ADJUSTMENT Although it is sometimes possible to reuse an old cylinder head cover gasket, in most cases it makes more sense to purchase a new one before beginning the procedure. Some vehicles may require the use of silicone sealant either with or without a new cover gasket. For more details, please refer to the cylinder head cover procedures in Engine & Engine Overhaul of this repair guide and refer to the gasket manufacturer's instructions.
See Figures 1, 2 and 3
For the intake valves: 1-4-5-8 valve clearance is 0.012 in. (0.30mm). For the exhaust valves: 2-3-6-7 valve clearance is 0.012 in. (0.30mm). The pivot locknut torque specification is 12-16 ft. lbs. (16-22 Nm).
