Well, I have the copper gaskets from Mr Gasket between my Hookers and the heads and I've used nothing but them all my small block career. I, too, use antiseize on the header bolts and use S/S allen socket head header bolts so I can torque all the header bolts to spec. And yes, retorque after a few heat cycles. One other note, make sure you have the correct length header bolts as some are too short with different headers.

I've tried Felpros, and Mr Gasket copper headers gaskets with mediocre results. I'm now using Percy's Seals4Good aluminum gaskets, the seal is great and they're reusable.
