Took the heads off and the cast iron heads need to be replaced or completely redone due to rust. The block looks to be in good condition and the pistons look to be decent, too. I will have the cylinders cleaned and honed or bored over.

I was able to get it to turn over. Looks like there was just surface rust keeping the postons from moving. Hopefully just cleaning and honing will do.

We'll see what the bottom end looks like!
