I can’t take it to insurance because it was a salvage title vehicle that I got and repaired. Insurance would give me nothing for it. Is there any way to check and repair without pulling the engine?

If the engine was running when it took water into the cylinders, it's done. One or more connecting rods bent, valvestem(s) bent is the usual outcome. I've seen a GM engine deform a connecting rod during cranking after a fuel injector stuck open while shut down, filling the cylinder with raw gasoline which, like water, is also not compressible.
If the engine wasn't running, you likely formed a rust ridge on the cylinder wall(s) while the engine sat. The rings hit this while you're turning the crank, and stop. A soaking with Marvel Mystery Oil in all cylinders might help loosen it up.
