As long as the ring grooves are intact and the top of the piston is un-damaged they should be fine. A little sanding with some green scotch pads should do the trick.Hey, speaking of forging, I just found out Tesla worked with some European company to build the best forging press on the planet....so far. Hot aluminum is injected into some very complex forms for large automotive parts....not too fast or it creates bubbles and not too slow or the aluminum cools....https://www.youtube.com/watch?v=8rWCTasV2t0
.....but even better than that. and I can't say it enough, will be the Pistons these fellas are making for a local G749 302 project........https://www.rosspistons.com/ More to come on that. Wouldn't want to take away from the birth announcement.
We have baby deer at the G749 farm. We've only seen a pair which is good news because they won't take away the glory from the big birthing news.

Triplets.

Don't get me wrong, I know how difficult birth can look but not many ladies will say they used a 4 foot hoe to get a piston out. The mechanic boys said if I put a wooden dowel under the pistons I could just beat them out. Since I farm and landscape, all I had was a 4 foot Italian hoe. My buddy Tony, god rest his soul, showed me more ways to skin a grade and move material with this ridiculous backward shovel, I knew it would get pistons out.

The stuff that came off the top of the pistons is laying on the deck. Looks like after aluminum.

The first one crowned after 30 hits. The second one only took 15 because I hit it twice as hard. The third one made me think that weeding an acre of garden would be easier so we only have triplets. I need a bigger hammer to get the rest out but I think it can be done. We have some tiny scratching on the pistons and from what I see in the 3 bores, where the rust didn't invade, this baby is a keeper.

If you have a sand blaster you can blast the pistons with "coconut husks" media, or similar . If you don't have one then soaking them in aluminum cleaner (bought at NAPA) for a day or two will help. Getting the ring grooves clean is a top priority for good function of the pistons.
