Sorry to give poor advise on the intake. The last big block I worked on did have coolant in the intake. Yes, it has been a few years. One last thought, you can always pull an oil sample and send it in for testing. It will show you in PPM (parts per million) how much coolant, if any is in your oil sample. Though not usually done on gas powered engines, it will give you a wealth of information on the internal condition of your engine. Good luck with your truck.

Well guys, it was a nice day today, walked out after work, saw a decent sized puddle under the truck. Got to lookin, and it is the water pump. Dang, but it could be ALOT worse. This sucks right now, cause im BROKE.

I've seen one Gen-VI and one Gen-VII bigblock leak coolant from headbolts. Both of them were leaking from the short bolts externally visible at the bottom of the head under the exhaust manifold.
I haven't had the problem with mine despite "abuse" (5000+ shiftpoints on stock valvetrain, etc...)
Dex-Cool has a very distinct smell. If you're familiar with the smell you're looking for it's possible to pick it up standing next to the truck without the hood even open in very small concentrations.
For your oil change - I might suggest that you drain the oil into clear juice jugs. Let it stand for a few days and any water in the oil will begin to settle out. Another sign, as you're pouring the oil, is the appearance of lighter strands or streaks in the oil. Oil mixed with water or coolant looks more like chocolate than soy sauce.
