Lol......its dead easy....head bolt sequence is the same as any engine and the timing is as easy as lining up the crank mark (its at 6 Oclock), lining up the cam mark (its at 12 Oclock), fit the belt with no slack in the right hand long run and tension (turn counter clock wise) until the marker is aligned with the mark for a new belt (4mm to the left for an old belt) and jobs a good un.

Head bolt sequence (torque = 25Nm +90 +90 +90) is as per above, use the reverse for removal.
I set the crank 90 deg before TDC (3 Oclock) on the 4 pots when doing heads as the psiton are all half way down the bores so there is no risk of valve damage
There is a green sealent (as used on the front cam caps on the Omega and often supplied wrongly by the dealer for the cam cover gaskets) that has to be applied between the the cam carrier and the head surface, use the right stuff or it leaks.!
If you change the water pump then when you fit the new one make sure you align the lug on the pump with the casting lug on the block or you wont be able to set the belt tension correctly.
I assume its the S20XE?
Ow yes, moved to chat because not strictly Omega related!
