Do I need a new Head and Pistons??Pics inside

[Brian]

Alright I have a incident with skipped timing and destroyed all the exhaust side valves. Now we got the head off and the Pistons have imprints on the top of them from when the valves hit them, imprints and some gouges in the tops of them but no actual broken off pieces, do they need replaced or can I do my best to smooth them out and be fine. Next the same thing the valves came back up and hit the head and put some imprints and gouges in the head, do I need a new head or can i just smooth out the rough spots. I have pics here, sorry they arent the best but you can see the marks made, for both the pistons and the head it was really only 2 cylinders that got the most damage the other 2 cylinders were pretty much fine. Let me know what you think, because i dont know if they can be smoothed or if it would affect performance somehow.

Take the head to a nearby machine shop to get their opinion. The pistons are fine as long as they aren't cracked.

So the pistons are fine as long as there are no cracks, because there are no cracks just imprints and some small gouges.

Dude no offence but your pictures suck. You should replace the piston's that damaged even with a used set. You can probably score some from dsm trader for like $20.00
