The main cause for bent valves is a failure in the timing chain or belt. When the valves and pistons are not exactly in sync, they can collide.

How do you know if a have a bent mechanism on my trumpet?
If you have a bent valve slide, or valve, or valve casing, they usually wont move. Valve's and valve casings would prevent the valves from moving, while bent valve slides wont easily pull out. If you suspect a bent valve, valve casing, or slide, try cleaning and oiling it first, valves and slides can become stuck with the lack of valve oil or slide grease.
What causes backfires and low compression in an engine?
Sounds like the valves are not closing properly. Something in the valve train is damaged. Could be a bent or broken valve, broken valve spring, broken or bent rocker arm, bent push rod, etc. Low compression combined with back firing thru intake would indicate a damaged intake valve component and back firing thru the exhaust would indicate a damaged exhaust valve.
