I bought this car and the owner told me it might have bent valves because the timing belt snapped. I bought the car anyway hoping to replace the cylinder heads. After looking at it I did see that the valves were bent, but the surface of the pistons had indentations from the valves about a half inch from the piston rings on all pistons. Would this cause a problem in the drivability of the car? Is this a lost case or do you think I have a chance to revive the vehicle? Pistons are moving up and down the chambers with no problem. Please give me your expert advise.

No, not at all. If there is metal sticking up then remove the metal sticking up on pistons with end of flat file etc.

Thanks for replying regarding the bent valves.I sent an image so maybe this will help. My question was, will the indentations or dings as you may call it on the surface of the pistons affect the operation of the vehicle as you can see. This is on all the cylinder's the compression still be some what normal. You guys do a great job helping out.

As long as there are no sharp edges on the dings then it will be okay. If there are sharp edges remove the sharp edges as that can cause detonation which is not good. Otherwise put it back together after valves fixed and happy driving.

Those are supposed to be there it's called valve reliefs so valves don't contact the pistons.
