This answer was rated:

hello- I just installed lower intake manifold 94 grand am 3.1. New gaskets and bolts. I misread specs and torqued 4 upright long center bolts to 18ft lbs thinking they had the same reading as the upper intake bolts. They should have been 110 inch lbs. Now what do you think and how bad is it and what should I do Thank you charles

Hi Im David , you need to take it back apart or the intake manifold will without a doubt crack.
