Stuck valve?? Exhaust is pulling backwards

What all makes the exhaust suck backwards.

I have no exhaust leaks. Im figuring a stuck valve, but which side intake/exhaust?

Compression test was bad, but could it be anything else. All cylinders pumped up about the same.

Maybe remove your valve covers and hand rotate your engine with a ratchet on the crank bolt. You'd see pretty quickly which valve(s) are problematic.
