Questions about head shims rebuild

[Bustamove]

Alright so from the top, I bought a 09 nytro 163 mtx6500km/4000miles, with what I'm told is a mcx 240 kit ready to go. Unfortunately I got screwed, got it home it sat for about a week or so went to start it up. Long story short, exhaust pumping out burnt coolant oil level is milky and over filled now. Hopefully rod isn't Bent, and crank is okay(can't tell clutches are so god damn noisy)

My questions are:
With the head shim is it an oem gasket above and below it? Or 1 gasket split apart, research has me more confused.

Should I replace head shim? With stainless or mcx aluminum? Pro and con to each? I emailed mcx and they want almost 200 cad for a new shim. Yet hurricane +others want 75usd ish for stainless.

Every bolt on this engine is torque to yield. Obvs head,rods, bearing caps, I'll buy new. But can you reuse the case bolts? Well we're talking about bolts are arp worth the money?

From the research I've done usually head gaskets go due to overheating or really pushing way to much boost. Anyone heard of a cracked head or block? My worst fear!

I'm coming from a polaris rmk 900, jury is still out if I'll like the nytro or not so I don't wanna sink a whole bunch of money into yet... but id like to get it running.

So you certain the gasket is blown? Did you do a leak down? I have seen many gaskets done with 2 stock gaskets and a plate as you stated but I would always buy what was made to do the job.... and I would replace the head studs if your going to tear it apart too.

No I haven't done any real tests yet, so I'm kindof jumping the gun. But I will be doing a leak down, coolant pressure test. But I filled the rad with about 0.5 liter of coolant ran it exhaust smells sweet and after sitting rad is dry and so is coolant bottle Again. And oil is milky. How eles do you think the coolant and oil is mixing. I googled failed oil cooler but nothing really came up

Pretty good odds based on that info.
