Bummer. Time for a rebuild. Suggest you replace every bearing in the engine with new, quality bearings.
Also suggest you totally flush the new crank with min spirits. You cannot over-flush it. Use a white plastic laundry tub and clean and change solvent until you see nothing in the bottom of the tub. Dry it with compressed air an clean again. When squeaky clean and dry, flood with fresh motor oil.

I see in one of the fotos that you have a pushrod with rub marks on it. The stock pushrods will bend under load and rub on the head gasket. If you have some extra coin available I would suggest getting a set of Modtop pushrods and installing them while you have it apart. They will not bend and you get full valve lift all the time. They also expand at the same rate as the cylinder & heads which helps maintain the valve lash adjustment as the engine heats up, less clacking when she's hot. I run a set in mine and they have a much nicer finish on the ball ends as well, correct hardness, wear is minimal, pushrod adjustments hold forever. :)

You have to drop oil pan and look at the pan .
The way oil pan designed it trap aluminum shavings.
While pan is out, check the oil pump, look at it while pumping the kicker to see if the gears move at the oil inlet.
Oan off, also easy to remove engine fr frame.

I am about to remove the gearbox. Having trouble with the flex coupler.
Thanks for the tips on the push rods and checking the oil pump.

Remember that you need to disconnect the swingarm to get the coupler off.

Got ready to remove the engine mounting bolts. Nice and crusty... don't want to move... heated them up and applied penetrating oil.

I'm assuming you already tried a big hammer?

Yep.... tried the big hammer. Didn't want to mushroom the ends. Going to double nut them on one end and try to at least get them to move. Have to pick up a breaker bar from Harbor Freight after I finish my "honey do list".....

Deja vu - someone else has this exact problem on another thread? Gobium said he can beat the crap out of the studs, they're cheap to replace. Also, use molegrips to try to turn the ends, not two nuts locked together.

That someone else be me. Thought I'd start a new thread on removing frozen studs. Just wanted to stay on topic.
