Torque for head bolts 1996 chev - 1996 Chevrolet Blazer

I have a factoys for this vehicle I will look it up
I'm am assumeing you have the 4.3 vortec
This is some what complex .There are 13 bolts in each head 3 different lenghts .You need 2 passes and there is a spicific order they need to be tightened in
The order works like this there are 7 bolts under the valve cover front to rear 12-8-4-1-9-13 and 6 more running down the intake manifold in line front to rear 11-7-3-2-6-10 .The 1-2-3-4-5 and so on front to rear that is how the # go so you need to move around it in a clockwise patten .First pass 22 flbs
The second pas they are talking toqure angles with the shortest bolts its 55 degrees beyond 22 flbs med L is 65 degrees and the long 75 degrees .this is torque angle
So at 22 f lbs and their is 360 degrees in a circle you need to move 55 -65 -75 degrees .For 3 differant bolt lenghts
Don't ask me why they do it this way but this is right out of the factory manaul for your vehicle
