You can also get high grade nuts that are half the thickness of the OE ones for even more gain live every 24 hour block of time like it's your last day on earth

I second the use of shouldered studs...Try hard to use them and save yourself a big headache....Standard header bolts will all leak eventually I've tried everything...Some are sealed initially but after a few heat cycles they weep...And if you crank on them they'll leak...And..You get the picture...
