what is the tightening sequence for the cylinder head bolts and what torque?

With any cylinder-head start from the middle and work out. going in zig-zags from the middle out on both sides:

10 4 2 6 8

7 5 1 3 9

The tightening sequence is in 4 stages:
(i.e. turn all the bolts in the shown sequence to stage one. Then agin to stage two and so on.)
Stage 1 - 30Nm
Stage 2 - 50Nm
Stage 3 - Angle-tighten a further 90 degrees
Stage 4 - Angle-tighten a further 90 degrees

I'm fairly sure there the correct torque settings but not definate.
