If you wanna check for any bent valves etc take your coil wire off and crank it over.
Listen for smooth cranking rpm's. In other words, listen for a normal sounding motor cranking over.
If the rpm is all over the place then you might have bent some valves or push rods.
But if the car runs ok and there is no audiable noise either at idle or cruise, then i wouldn't sweat it.
