This is excellent advice. I replaced OEM with V&H Big Shots and found everything he just wrote to very accurate and thorough.Removing the old gasket is interesting. Many people think it missing. It is there. It is a soft composite metal outside gasket that fits nicely in the exhaust port. A dental pick, paint can top remover, a screw screwed into it, a nail all have been used to move/distort/remove the old. Put some towels on the pipes to keep from scratching them. Another pair of hands advisable. Depending on how thick the flange plates are you may need a washer on each stud/nut to prevent bottoming out the acorn nut. Don't get crazy, don't over tighten, many have broken studs.
Install new gaskets, install all bolts before tightening. Leave the bolts on the rear bracket loose until the front engine nuts have been all tightened. Alternate tightening of nuts so the flange goes down even. I probably used some anti-sieze. Only ever lost one acorn nut. After a ride check/tighten again.
Use a torque wrench to tighten the acorn nuts. You may need an extra washer to make up for any difference in the thickness of the flange/collar of the header pipe, assuming the cruzers are not slipons. I'm assuming they're not since you're talking about header gaskets. And I would agree with the anti-seize.thanks alot, i didnt even think about new gaskets. and thanks for the little things to make it easier.
