Blown head gasket?

I think i may have a blown head gasket, I have water in my oil.. and it looks like some smoke around my passenger side exhaust manifold.. I haven't really paid attention to the coolant since i haven't driven it since the motor swap.

Check your plugs and coolant but I'm going to agree it's blown or cracked. Only oil should be in oil

Drain all of the coolant including the 2 lower block plugs. Drain and replace the oil and filter. Use cheap oil. It isn't going to see much use. Don't add any coolant back. Start and idle just a few seconds longer than it takes to get full oil pressure then turn off. Should be good until better weather.

They are just above the oil pan rail about half way back the block. Usually 1/2 or 9/16 hex head.

those probably aren't coming out then... I tried to remove some for my knock sensor and oil pressure switch and they are stuck good.
