Default Header Installation Tips?

Does anybody have any good tips on installing header to ensure that there are no leaks. Is there a tightening sequence? Thanks

I don't understand the problem with header leaks. I either never have them or can't hear them over the noise of the motor.

A flat true header flange a new Felpro gasket and heads that are clean and I just use ordinary $10 header bolts.

I use dead-soft aluminum gaskets on the collectors to prevent blowouts.
