felpro gaskets do not require retorquing, nor to most any except copper without hylomar, unless you overheat it. After any overheat, it is very good practice to retorque immediately to see if you can save the headgasket. The PT in felpro part number means permatorque, the blue stuff on them is machine printed rtvish stuff for a self setting gasket seal. The gasket is resistant to compression, too, past the specced compressed thickness at specified torque.
