Like warthogdriver stated you're torquing to IN / LBS.
This is the torque sequence from the front of the engine -
Pass. Side - 7 1 3 5
Driver Side - 8 4 2 6
Torque specs -
First Pass: 26 in/lbs
Second Pass: 106 in/lbs
Third Pass: 132 in/lbs

i didnt catch that mistake in time when i was retorquing my lower intake bolts and over tightened one on the passenger side and broke it off in the head. i tried easyouts which wouldnt remove the bolt, probably cause of the loctite. i ended up drilling out the bolt and retapping the hole. engine coolant sucks right down the radiator now and puddles below tailpipe along with some white smoke????????? any help please

I finally found the intake unit in a scrap yard. Lucked out and for Just $86 foud the entire intake unit, computer, all doors and bumper moldings, with some interior parts. One man's trash is another man's...

I'm experienced enough to tackle big jobs on my 1999 Blazer. The only tool I haven't used is the Cam Bearing Removal and Installation Tool. I would very much appreciate any links or videos showing the use of the above mentioned tool. I should have done the cam job before I installed the engine.

If you plan on keeping this vehicle for awhile get the Fel-Pro metal intake gasket kit. It comes with all the gaskets, and RTV sealant.
Federal-Mogul - Fel-Pro Intake Manifold Gaskets
The plastic ones do not last. They break around the cooling ports.
Your going to have to guess on your torque settings. Unless you have a real high end torque wrench (snap on) it will not be accurate at the low settings.
If your intake is pitted around the cooling ports do not do what the Handymanlyness guys does with RTV sealant. Use epoxy instead.
Here is a better guide:

Yeah my brother made that same mistake on his when he installed his new crate motor but tell me something, I'm curious how you know your pump bushing needs replaced. Just wondering.
