a bit more info will be rather helpful. what is the block and cylinder head casting numbers?
and
how much time & money can you realistically drop into the project?
can you do most of the engine assembly yourself with tools you already own and in a location where you can work under clean well lighted and safe conditions?
OR will you need to pay a machine shop?
Its up to the guy who assembles or builds an engine to verify that the machine work on any components been done correctly,
theres unfortunately a good percentage of machine shops that don,t employ people that have the skills and experience,
or the tooling to do the work correctly, or in some cases and desire or capacity to accurately measure the components accurately,
before and after precision machine works been done.
I'd bet 90% plus of the people who have a machine shop do precision work on any major engine component, like that
would have naturally assumed that the precision machine work was done correctly,
and simply assembled the engine without thinking a second about that work being done correctly.
this is one reason I strongly suggest most serious engine builders may want to have some precision,measuring tools,
and spend the time and effort to check that machine shop work you paid good money for, was in fact, done correctly ,
taking the time too verify the precision machine work was done correctly,
takes a good deal of the time required, in any engine build
(vs slapping parts together out of the box and wondering why it never quite runs up to your expectations)
and yes you probably could use the block in its current condition and find the engine runs,
and most people would never know the engines measurements were not correct or why the engine did not produce power to its full potential,
and the results might be so close that it would hardly matter ,too most car/engine owners.
but that engine block machine work ,being off specs, does not mean its been built correctly either

A stock and original 1982 engine will more than likely need a rather extensive rebuild , by the time you buy new pistons, rings bearings ,get the block cleaned, decked, bored, line honed,have the heads rebuilt with ne valve seats and valve guides and valve springs, buy a cam & lifters and new rockers, a timing set, gaskets etc.get the lower end rotating assembly balanced and other machine work done ,
and you replace the valve train, and cam and lifters and get a 3 angle valve job, the total cost won,t be dirt cheap.
once you calculate all the parts needed and machine work required I think you may want to think through your options
theres a very good chance that if you write down the price of every component youll need and all the machine shop costs ,
youll find much to your surprise its going to cost a good deal more than most guys might imagine to do things correctly!

LOOKING FOR A DECENT AUTO MACHINE SHOP, or BODY REPAIR, or CUSTOM SHOP??
the best route to take is by joining a local car club and talking to dozens of guys at the local car shows and rod runs and at the local tracks,
GO TO THE LOCAL TRACK, AND GO TO LOCAL CAR SHOWS<ASK LOTS OF QUESTIONS, TALK TO LOTS OF PEOPLE, you'll eventually find out which machine shops AND BODY SHOPS do quality work and which do sloppy or slipshod work, or take money and never do the work correctly at times.
ALWAYS stamp your parts with your PH# number or some other ID and take clear detailed pictures and get signed receipts listed parts, dates,costs and expected work to be done and dates due and take a picture of the guy your talking to and get the receipt
look around the shop! if theres dozens of cars sitting outside , rusting, or stacks of greasy engines you probably don,t want your car joining them.
Now I'm certainly not suggesting you don,t do the project,
I'm just suggesting you go in knowing the cost to expect and realize there may be valid options depending on what you want too accomplish!
I used to drive from south florida out to Colorado near EAGLE co. to hunt (2300 miles one way) in a 1989 ford crew cab dually with a 460 for almost 17 years until I sold it, so I'm rather familiar with hunting colorado/
