You know you can't use a steel shim gasket with aluminum intake, It will always leak.
At some point sooner than later you will have a major mess on your hands.

I knew I had a copy somewhere of the 6 pack intake gasket bulletin.

Yeah, the guy who owns it bought the shim gaskets and put them on. Like I said, I’d have to cut the intake if I switch to paper gaskets, and I don’t want to do that.

And, it’s been working since 2015. And now that I typed that it will screw me hard!.
