Timing Cover Gasket Replacement

does anyone know the torque specs for the timing cover ? Is it just hand-tight (via a ratchet , of course ) and tightened in a star-type pattern ?

I know that there's 3-4 bolts at the cover's base , plus the ~6 bolts which retain the water pump , as well as ~7 bolts at the oil pan ; is there a torquing-sequence ?
I don't want to go too crazy , as the cover and the pump housing are aluminum .

Thanks !
