I have the mondello Windage tray in my SBO and felpro metal intake gaskets sealed with a good amount of RTV on my Edelbrock 7111 intake. The intake runners and coolant seem to seal awesome getting the front and rear to seal and not leak oil different story entirely.
Previously had the windage tray with fel pro fiber gaskets had vacuum leaks I could never find oil leaks and seeping coolant
First set up I had was a factory turkey tray and I believe I was able to seal that one I think
As a disclaimer though I am terrible at dealing gaskets it’s sad to say but I’m not sure I’ve ever had a dry gasket on the first shot one day though maybe
