normally 110 nueton metres. use nut lock and once you have torqued you will feel if you have to tighten it a bit more.

According to my haynes manual for G-S reg, 1989-1998 it goes as follows,
Stage 1:- Tighten all bolts by hand until bolt heads just contact cyl. head.
Stage 2:-Tighten all bolts to 40Nm or 30lb ft.
Stage 3:-Angle tighten all bolts a further 60 degrees.
Stage 4:-Angle tighten all bolts again a further 60 degrees.
Stage 5:- M12 x 140mm bolts ONLY angle tighten a further 20 degrees.
Hope this helps everyone, sorry it seems longwinded but that is how it's written in the manual.

assuming this is the "C" engine 8th digit on VIN plate. Use new bolts. torque first step to 25lbs, 2nd 50lbs, then 3rd 50lbs, then 1/4 turn.
