Oh sure, i've used pistons in worse shape then that. Those are cosmetic at best and wont effect longevity of the pistons. They're .030 over right? Those will sell no problem, hell if I didn't have 5 sets of forged pistons i'd probably grab them from you. Bring them down to the shop and i'll toss them in the washer, you'd be surprised at how little you'll be able to see them once clean.
Also dont toss that cam, it's still salvageable and can be refreshed for not too much money. Hell Joey might even buy it from you.
As far as 331, well, we've discussed that before
