hi guys im putting together my 97 grand prix intake gasket, can someone tell me the torque specs to use for the upper and lower gasket bolts, and i alos need the torque specs for the rocker arm bolts if any, please help, its a 3.1 v6 SFI.
 


89 in lbs + 30 degrees for rocker bolts, you need to buy new ones.

lower intake bolts are 62 in lbs then 115 in lbs.

cant find any mention of the upper.
 
im sorry, can you tell me in ft lbs, and what does 30 degrees mean. and on the lower bolts, why do i need to tighten them twice, or what u mean by 62 then 115. im mostly worried bout the rockers and the lower, but im not good with the conversion, so do you know the FT lbs.
 
From the PM:

divide by 12 and theres ft lbs.

typically if the numbers are in inch lbs, its because a typical ft lb torque wrench wouldnt be accurate at those levels.

30 degrees means you must use an angle meter and turn it 30 degrees.

You tighten twice to prevent warpage and ensure even pressure. what you do is tighten from the inside out to 62 inch lbs on the first pass, then 115 on the second.

Again, ft lbs wont help you much.
