My oil is milky and white smoke poaring out the exhaust. Its more likely that the head gaskets are blown or that the block is cracked

These aluminum blocks, I'm sure there's been some cracked ones.....but I've never seen or heard of one that was a street car and I bet there's literally a handful worldwide.

Does your coolant boil over and overheat?

Most likely you blew a head gasket. When I blew my head gasket, my oil was milky and white smoke. Mine was also over heating, (loss of coolant leaking into the head). Your best bet is going to autozone, rent a pressure tester, pump to 13-15 psi, I'm not sure which, and see if it leaks down at all. When I did mine, I could see coolant leaking out the head. So mine was pretty clear, others have not. I doubt you cracked your block though, although you might have. Good Luck

Does the exhaust fumes smell sweet like coolant? If so then yes most likely you have a busted head gasket.

You can do a leak down test to find out which side is blown, but I would go ahead and replace both at the same time.

definetly do a leakdown test. has the coolant in the radiator went down any? its possibly a blown head gasket/ warped head.
