Ok, long story short, my timing was off. I pulled the head off tonight and found 6 bent valves and some minor damage to the pistons. I took pics of the damage, because I still think the pistons are salvagable. My car has 104k on it and right now I just want to be able to drive it to work and back, no extreme mods or racing. I know I either have to replace the head or rebuild it, but I want to be able to not replace any of the bottom end as of now. By looking at the pics, does anyone know if the little damage will be a major problem?? The small radius' on the pistons where the valves hit are very smooth, no sharp points, so I don't think there will be chance of hot spots and detonation. Opinons on whether they are still good or not????

you can probably get away with just rebuilding the head... none of the marks on the pistons look like anything more than a slight impression.

i agree with the others too. when you get it all back together try turning it over by hand first (ign disconnected) just to make sure nothing will hit before you turn the motor over for real.

Valves are cheap from the dealer. Well, as long as you don't have to buy ALL of them.
And you don't need a spring compressor to get the retainers on/off. Just need another set of hands.
