can i use these pistons still.

Hey got the head off tonight seems to have only bent the exhaust valves. Im going to rebuild the whole head or buy one that hasent been messed up but do you guys think i can still use these pistons there little nicks not deep at all i just need to get like another few thousand miles while i build my other motor im low on funds so may take a while and be a winter project but just wanna get the car out and running kinda decent this summer. thanks for any info you can give. also one more thing when i got the head off i noticed these four little hard lines in a vertival line not hooked up to anything what are these thanks.

I would use them, but is there a gouge on the lower right hand side of cylinder 2s piston?... and the hard lines... I'm not sure what they are, ill go look in the morning if you don't get an answer.

I'd use them if you only needed a couple hundred miles..Just make sure you smooth out the sharp ledges to prevent pre-ignition. because that would be very very bad /ubbthreads/images/graemlins/ooo.gif Thats just my opinion.

If your talking about the hard lines I marked in your picture (my paint skills are awful) They are for your FPR solinoid and FPR
