So I finally got the head off of the 05 ss/sc I bought about a month ago and I was hoping to bottom end would be fine but there are marks on the pistons where the valves tapped them when the car jumped timing. I'm not sure if I need to replace the pistons or if I can reuse them. I need an expert opinion. If I need to replace the pistons I might just sell the car.

They will make good ash trays, or cup holders. As deep and sharp as the divots are I wouldn't run em.

You should just get diamond pistons to make it stronger anyway.

I wasnt really planning on taking on doing the bottomend just planned on putting a new head it and be done with it. I dont plan on keeping the car I bought it to fix it and sell it off.

the marks aren't that deep file the sharp edges and blend in the best you can should be fine plenty others have done this

I can't really tell how deep/sharp those marks are. Doesn't look too bad.

These are my pistons at 78K miles for reference...

We just cleaned them up with a wire brush on a drill, and used a 3m cookie disc to blend in the notches ! they where not to bad... we also put in 8 intake valves ourselves.. put in head studs and a new gasket. over 5000 miles ago.
