Those 083s were not on the crate motors. They might have been on some of the very early crate engines back then but quickly went away. Instead, they used the 217's which were the same part number, but different casting #. I still have the sales receipt when I ordered a new set of 083's from the GM dealer only to have 217's in the box. Dealer told me the "replacement head" for the IROCS/Z-28's/Formula Firebirds was the 217's.
The 083 were on 88-91 350 cu in Z-28s, Formula Firebirds and IROC's. And they are rare. Most of those Camaro and Firebirds had 305's in them (081 Head). The boat motors had 217's....
Don't use the 217s, they are even thinner than the 083's, which have thin decks and are made out of pop can material. Both the 083 and 217 are of the scalloped type, similar to all the water leaking 624's that we used to run. The 083s are an OK head for a Stocker but hold your breath kind of head for Superstock.
Oddly enough, if you look in the guide you will see some other numbers listed with the casting #;s. One of those #'s is 10159552. Seems to be a 552-casting number but it's not. Turns out that is the Part Number when ordering a new 083 head . (Below)

Back when you could still order them.

Those heads have become rare. Back in the 2000s it was known they were pretty good for the street kids were hand porting them so those are ruined if around. My brother had a boat with a 350 when we went through it had them BUT must have been used cores valve guides were opened up for larger stem valves. Beware you may be looking at replacing valve guides with a set of boat heads.

Good luck Trey I found a set about 2 years ago and paid $500 for them and another $250 to get them shipped. They are the unicorn that we're all looking for these days.

Re: Chevy TPI Heads #14101083
 

When looking at your new casting, have a look at the water transfer holes in the decks. (The ones we always have welded up solid). You can look thru the holes and see how thin the 083 decks are. Some of these castings are super thin in those areas and they will end up like mine did. After 3 times of having various areas welded back up and repaired... I finally scuddled them. 8000.00 for a year-old set of boat anchors.
