Intake Manifold Bolt Removal??

[slikside]

I have a '72 C-10 350 with 250k + miles on it. The engine is all stock/original...never been rebuilt or even apart to my knowledge.

When I replace my water pump in the next couple weeks, I would also like to remove the smog pump and the bracket to which it is mounted. This bracket is mounted to the block in 3 places: water pump bolt, and two bolts on the intake manifold.

Here's my question: Is it reasonable for me to think that if I loosen ALL intake manifold bolts in the reverse order from torque pattern (each a little at a time), remove the smog pump bracket, then retorque all bolts in sequence, that no harm would be done? I want the smog bracket gone, but not at the expence of having to actually pull the intake manifold to clean and reseal etc, etc...

And how about those two manifold bolts, do you think they are longer than the others and would bottom out before tightening with the bracket removed?

Thanks for your thoughts/suggestions...would you or would you not?
