intake manifold bolt torque question

I have not ran the engine since loosening the intake manifold bolts. If I torque them back to 20 ft lbs I should be good to go then right? I have tons of intake manifold gasket sets laying around fel-pro, bought them up when I worked at a parts store and got 30 percent off. I could easily change the gasket again, but since I have not ran the engine since loosening the bolts I was thinking it would be ok if I torqued it back to 20 ft lbs.
