The Pantera is really one of the few cars that can use tall stacks. The GT40 put a plate over them but used short stacks.
That just provides a place for it to accumulate. I'd rather keep it in the carbs. It's nice to know where it is and is a pretty simple solution?
You can also hear how the carbs definitely have a "whistle" to them. That's an idiosyncrasy of IDA's.
