tonight i took it out for a ride (yay), only to have it over heat after about half a mile (boo).
the temp gauge shot up quickly and the coolant in the tank started to bubble. however, cranking up the hot air resulted in just.... air. not hot. weird.
i must have a line crossed or something. prior to taking the motor apart i had put about 50 miles on it without any issue.
anyone have an idea? maybe something obvious?
edit: NEVER MIND
i'm an idiot. i called a friend of mine and told him the story and he said "air bubble". yup, i didn't add coolant through the upper hose, just the coolant tank. it took nearly two gallons and suddenly, amazingly hot air from my vents.
again, i'm an idiot.

If you look down at the crank shaft on the drivers side is a arrow. On the pulley is a mark that has before and after degree markings, the center is TDC which is 0 degrees. Now the next thing you do is turn the motor by hand by placing a wrench on the center nut of the crank shaft and turn clockwise, never turn counter clock if you miss it keep turning. Once you line them up take out the front drivers side spark plug and ensure the piston is all the way up at the top, if not then you are 180 degrees off and you need to turn the motor by hand one more time back to TDC and you now should have the piston at the top. You can place a long screw driver down the plug hose to see if it is up to the top.

1. No on the guides.
DESCRIPTION - VALVE GUIDES
The valve guides are made of powered metal and
are pressed into the cylinder head. The guides are
not replaceable or serviceable, and valve guide reaming
is not recommended. If the guides are worn
beyond acceptable limits, replace the cylinder heads.
2. Cams should be reusable.
Should just need the sprockets, chains, and tensioner.
You really need to download a Service Manual: http://pdftown.com/Dodge-Durango-Service-Manual.html
