IMO more important than the gasket is the understanding that most gaskets compress for the first week or two of use, so retighten frequently during that time.

I have heard good things about 1406's and ultraseals so i guess it may be a toss-up.

I don't like the copper gaskets. I never had any luck stopping leaks if I reused them. I buy the Jegs part number 720-5965.

Go to Auto Zone and get the percys reusable header gaskets.
I've had them two years and had them off three times and never had to retighten or any leaks.

Id go for copper. On my exhaust flange gasket (the one at the bottom of the header) I put in the black mr gasket "paper" one and it blew out within 6 hours. After that i put in a jegs copper one and its been perfect ever since.
