B&S engine wont hand turn more than halfway

I didn't know if maybe replacing the complete cylinder head might be the way to go. I can find used on Ebay for about $55. Not sure if the dings on top of the piston would be an issue.

and the bent rod?

Dont think there is a bent rod. Just broken valve and dinged up top of cylinder.

Stick a ruler across the top of the bore
At tdc the piston should just touch the ruler.
If it is short then the con rod is bent .

when one has dings that big in a piston the force has to go somewhere. Usually into the connecting rod. At the least you are looking at a head, connecting rod, piston, rings, and valves. If the guide or seat are damaged, or the bore scored then the engine is junk. By the time you price out all the parts, you are better off with a new engine or a good inexpensive one from a donor. I priced out parts on a high hour engine a while back that still ran. Parts cost too much for a rebuild to be economical. Good luck.
