Looking into the windage tray for my 383 auto with a stamped 402 oil pan , lots of different opinions , are longer bolts required with the molded windage tray , and also have read some use sealant and some do not .
I’ve used the Summit windage tray that is also a gasket so it’s one piece on my last 3 builds. Really easy to install, reusable and no leaks. Oh and I’ve never needed longer screws with any windage tray.
