So you're just going to retorque and see if that fixes the problem? I guess it's worth a shot.

It's not a big ordeal, just grab a torque wrench and go through over each head bolt. If you used ARP bolts/studs, I'd set your torque wrench at about 100lb-ft and follow the torque sequence.

Same for the intake manifold, set at required lb-ft spec, and go through the sequence.
