Got a new Large BGE. Will start it up this weekend. I've heard the newer GBE's have gaskets that may not take to high heat, at least without some "seasoning" with a few cooks of lower temps. With this forum's vast experience, is that so? Should I wait to sear my first ribeye (I'm really looking forward to that)? Any recommendations as to a first-cook or first few cooks? If there is a weakness in the factory installed gasket, is there some recommendations as to a replacement gasket for high temp cooking? I want to break it in right if there is some break-in criteria.
