I've installed these with my headers, 500 miles, so far without a re-torque, no leaks. Should I retorque anyways? Or are they set? I'm impressed already, usually with old-school gaskets I'd have a leak already. I'm gonna put an X pipe on this weekend, so I'll be under there, but you know the drill for tightening header bolts, starter remove, motormounts, air intake, jack engine, yeeesh!
