All Honda engines can bend valves when the belt breaks. Honda engineering dept. told me once all Honda engines are interference engines. Manual trans vehicles are more prone than automatics. This is because manual trans vehicles in gear with the clutch out will keep the engine spinning until the clutch is depressed. Automatics just die less time for the pistons to hit valves.

Just to make you fell a little better your 1.5 engine usually does not bend valves. It's easy to check, pull the valve cover and feel the cam followers. If any are really loose the valve on that cylinder is bent. You can rotate the cam and check the clearance too. Any loose ones are probably bent. The last way to check is to put a new belt on and fire it up. After that compression testing will verify if any valves are slightly bent. I have seen engines fire up run for a while(days or weeks) then have a weakened valve head snap off and toast the engine. If you want the valve clearance inspection or timing belt replacement instructions from the service manual just ask.
