Thermostat gasket leaking AGAIN!!!!

I fought the leaky T-stat housing battle with a recent big block build. Tried everything mentioned until I found that the Felpro gasket was de-laminating and leaking through the layers. Finally tried a gasket from "Real Gasket" company for $11.00 and problem has been permanently solved!
