Take this for what its worth as I haven't done a SBC stroker. Most of my engine rebuild epxerince is on 65 GTO's ...and I would just stay with of the shelf full dish pistons to keep it simple...
From my understanding you want .035-.040 ish quench for a 383. this depends on the compressed head gasket thickness

I would work with your machinist to keep it within those specs depedning on compressed head gasket thickness of the actual gasket you use, but yes typically (with compressed gaskets being .030-.040) I'd think you'd be at zero deck or damn close. If you have to do a future rebuild I woul dsuspect you can either get custom or made to order pistons or machine what ever you may need (within reason) off the top of the piston.
Hey if you do this rebuild right, that will be 10+ years down the road, Rick will be reinstated on the forum and tell you everything I just said is wrong.... hey no reason we cant still have fun here...
When posting anything about "how to build a SBC" everyone has their opinions and experience. As many could, I could also post my opinions and experience on SBC engine builds.
I know a lot about the quench, piston profile, zero decking decisions, general engine building................It is not simple and there are so many factors to take into account before making any final decision.
But in the end, If you want it done right discuss all questions with and experienced engine builder who is operating or has operated a successful engine building business with easy to acquire references. One who dyno's his product himself!
Anything else is merely opinion..........with NO references!
Ricardo is one of those with Opinion only. Lots of them!
He thinks because he plagiarized others writings and posted somewhere on the internet (what he thinks are his WHITE PAPERS) and all over this forum, he is some kind of expert in all things SBC....................Well he is not.
He probably hasn't ever actually built one himself and if he did it most likely was over 40 years ago if not more based on much of the info he copies and pastes here.
One thing to take note on, Who else dictates opinion on that subject other than him?...............Wait for it..................
I have read virtually ever book on SBC going back to the '60's...........Does that make me an expert? No not at all. All it says is I read a lot of books.
Opinions on Materials, components, design of a build are like A $ $ holes..............everyone has one but unless they are a professional at that subject with years of real life experience their opinions are only that.
