WHITE ON MY DIP STICK

I bought a 360 form a guy a few years ago. He got it running for me before i bought it. It sat for about a year. I took the valve cover, heads, intake & oil pan off to check it out. It was very clean & you could see it didnt have much run time on the rebuild. Ok fast forward. I put all new gaskets on. Put it in my car & got it running. I noticed a water leak on the rt rear where the intake meets the head just below the last intake bolt. There was no water in the oil. So i got a new intake gasket kit & put it on. Put water in it & just enough to see it show up in the radiator tank. A few days later i wanted to start it & adjust the carb. Before i did i topped off the radiator with water. I started it & adjust the carb. It was running way to rich. I shut it off & a few minutes later i tried to start it again & no go. It has spark & fuel. Just for heck of it i pulled the dip stick. It looks like i dipped it in an off colored milk. Any ideas ? I hope its not a cracked head. I cant imagine it because it sat apart for awhile & this past winter it sat in the car with no water oil. Bad head gasket ? Another bad intake gasket ?
