Head bolts torque pontiac vibe 06 - Pontiac Cars & Trucks

SOURCE: head bolts torque settings

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.
