You haven't fried your gasket already have you? The standard gaskets are fine but I install them with 3m Super 77 spray adhesive which is what they do with the nomex gaskets. Scrape the old gasket with a scraper and then get chemical gloves and a bowl of laquer thinner (I know they say acetone but the distributor has told me laquer thinner works best) and a scotchbrite pad and scrub the rim super clean. The wipe it down again before installing the gasket. If using the standard let it set for 24 hours before heating and do several low heat cooks before goig volcano with steaks. If going nomex or standard and using Super 77 it can be used about 2 hours after install.
I just installed new gaskets on both my large & XL BEs.
