How easy should the crank be to turn with all the caps torqued? I have to turn it with a ratchet to be able to turn it. I've heard in some places it's supposed to be able to turn with your hand.

It should turn easily by just grabbing the snout on the crank. assuming you lubed it up properly. standard bearings on a warn crank could not be tight unless they're incorrectly marked.
Did you seat the thrust bearing with a deadblow? it shouldn't cause this but there aren't many things you can get wrong.

I did not seat the thrust bearing with a deadblow. Everything is properly lubed and all main caps came from the machine shop labeled and arrow pointing towards the front of the engine.

X2 w/440. You should be able to turn the crank by its snout fairly easy. Once you get pistons and rings installed you may need a ratchet or breaker bar to assist. Crank only should spin easily.

so what am I doing wrong here? It's standard bearings on a untouched crank.

You're probably ok, it's normal to turn easy but it's not like you can just give it a spin and it keeps turning.
If you can grab the snout and with a little effort turn the crank I'd run with it. if you need tools that's not good. it doesn't mean you're going to have a problem it just means something isn't quite right, but it might correct itself.
Check your thrust bearing and see if it's rubbing. to seat it you loosen the cap a little then pound the crank forward and backward a few times before you tighten it back down. it's just a common procedure it may or may not help.
If your machine shop didn't check your crank bores then that's probably your problem. normally you have it checked and align honed if necessary. since you're doing a stocker build and not wanting to spend a lot you're probably ok. it's just not ideal.

I'll see where I'm at with the pistons in. Ill try spinning it after each piston goes in.

the problem is it's hard to describe something that's measured in inch pounds. it's safe to say if you cant turn the crank with one hand then something is wrong. if you can it but it's stiff it might be a little off but should be ok.
when you start putting pistons in it's going to get stiff fast. you'll need a wrench after a few are in. that's normal. be sure they're oriented correctly and oil the rings up really good . dry ring grooves are the cause of most broken rings.
