Real gaskets work awesome. never had any issues, reusable to boot. works well if someone previously overtightened or bent the rocker covers.

Don’t believe the hype. I’ve spent a fair bit of time replacing these gaskets on customers planes due to leaks. Buy the standard gasket, put the approved sealant on them and you won’t have leaks.
