Al. header gaskets? Anyone used them?

[Rev]

I seem to develope header gasket leaks every 6 months or so. I may not be that good about retighteng the bolts often enough. By the time I hear that "tick, tick, tick" sound, the gaskets already blown. AutoZone sells those "dead soft" Al. gaskets for $40. They claim to be blow out proof and to be reusable. I'd be willing to pay the $40 if I was sure they would last and not be a waste of $$$.
