strange isnt it??
Alrthough,, the Early 2wd head bolts were different wernt they,
so perhaps there is a different sequence for that???
Although the way i did it deffo was for the 90 spec 200 block engine, as
you can see at the bottom of the page...
strange! but If you left them all at 180 degrees, thats no
guarantee that they are all the same tightness? as some differences in metal??
so making them all to 110 NM is to ensure even torque??
as a side note, i looked Also in a normal sierra manual, and they say
to do the 2ltr pinto head bolts to 115NM!!!
