How best to free engine that has sat for yrs and rings stuck

How best to free engine that has sat for yrs and rings stuck?
Tried soaking bores repeatedly in wd40 and marvel miracle oil stuff, but still wont hand crank (plugs out)
Not sure what to do next as stripping engines these days is so insanely expensive
Its been my car for 40 yrs and was running ok around 10 yrs ago - dry stored in a garage
Starting to re-commission - brakes are next once I can free engine, flush cooling and change pipes

I would it right to the brim with diesel, and leave it for a good long time to soak.
This - plugs out, sump off.Then leave it like that.
If you take the sump off, it'll drain back out.

Take the head(s) off and have a look inside?
If the rings are that badly stuck then presumably there's corrosion in the cylinders so it's likely to need some machine work anyway? If it's a 40+ year old engine it's presumably not going to be that complicated
IRON + ALLOY V8 and they dont like having heads removed + v expensive to recon...so hoping for a soak method - about to put more warm marvel miracle oil in - if that doesnt work - may try hot diesel in bores If the rings are that badly stuck then presumably there's corrosion in the cylinders so it's likely to need some machine work anyway?

As iron block and presumably aluminium heads I'm wildly guessing a hopped up SBC or something, but 'expensive to recon' makes me think something obscure and thus now I'm curious...
On YouTube plenty of people take cars from the grave not run in 40 years and deliberately with a tiny set of tools off they go. No new parts only fresh fuel / no oil change or belts either.
Anyway vice grip garage is one - love his vids. Frozen engines. He gets them all going and then usually has an 600-800 mile highway drive. Not sure how they do that in the US as these are NOT MOT passable cars.
Another one for frozen engine is brake fluid down the spark plugs.
Have you really tried to turn the engine off the fan? This is what they do in the USA. Another is the big breaker bar and slowly over hours back and forth to eventually get full cycles.
One car had been literally in floods countless times over decades with loads of water inside the engine. It still got running within an hour....
There is a cult thing that it’s huge fun trying to get something so ruined it’s likely scrap but get that big block running.
Another does it with American semis (trucks) most recent I saw was a pitbull with 680,000 miles left for 20 years. It started in 20 mins and they didn’t even bother changing the fuel (why waste what’s in the tanks...) so they took that big diesel for a full on Italian tune up on mountain passes plumes of black smoke but it slowly cleared up as the motor got nice and hot.

You should sample some Zip Ties & Bias Plies for a slightly more Canadian redneck version of similar philosophy. The sheer mechanical abuse the old American V8s will survive is remarkable.

No need to go US! I had one, a Triumph six, that had sat out in the rain with no cylinder head. An oil and white spirit mix in the bores, a daily turn, both ways, and it was going all the way around in a week. Slap a head on it and I still have that engine running in a test rig.One car had been literally in floods countless times over decades with loads of water inside the engine.

Out of curiosity, what is the engine then?
