Edelbrock Intake Issue

Buy this. Expensive but they dont leak. I put them on everything now, tired of messing with the old junk.

I tried a bunch of different gaskets and tried sanding both the surface of the intake and the thermostat housing cover and it would always leak. I then bought that Billit housing and it’s not leaked since.
