Top of piston Damaged?

Top of piston Damaged?
My timing belt broke as I was driving 40 m.p.h immediately neutral the car and pulled over, removed head off the engine inspect intake and exhaust valves no damage or bending or breaking from a visual inspection, but tope of my piston from the intake side has the valve deep scratch\mark but the piston is not deformed or broken/cracked its away from the walls and ring, is it safe to just put a new headgasket and timing belt or would that bit o damage cause loss of compression of sealing between intake/exhaust/combustion? HELP SOME ONE

If the piston Is marked its a good guess the valve bent.
Take the head to a shop and have them disassemble and inspect. Might as well put in some new valve seals and check the seats.

do you know how much that could cost to dis-assemble & inspect or new valves and seats, also does that mean the cylinder would not perform like it should, and would the machine shop calibrate valve gap because I don't have a calibration set

Just so you know I bent every single valve in my head, zero visible damage to the pistons, except one tiny piece of carbon knocked off one piston. My belt didnt break, it slipped a **** load though. Even if your valves dont look bent, theyre bent if they left a mark

thanks guys I think im better off taking head to machine shop and have it re done it may take longer to put it back on da streets but its better to do the job once and right the first time then having to do it twice, anything different I should do as far as putting it back together for better performance/ durability

wouldn't I bent the valves if timing belt was broken and I proceed to do a compression test I wouldn't have an idea if what valves are in open postion and compression would just ram straight into them?

Re: Top of piston Damaged?
When valves bend they don't seat right. So if you did a compression test you would find low compression is a cylinder and that would tell you if the valves may be bent.
If you did a compression test and had full compression even across all four cylinder then you just install a new belt and Keep on cracking that mad tyte 4th gear VTAK, BRO!
