Very Easy to overtorque, take the pan off and look at the holes for any distortions, take a ball pean hammer and gently tap down and raises in the pan and re install with new gasket, I think the torque for this is around 15ft lbs but not sure, no need for a torque wrench, just snug them evenly and tighten in an offsetting pattern like you would do when tightening head bolts
