headgasket not sealing?

ok so i built my motor over the winter and it has one race on it now.. and other day i changed the oil and it came out very milky and pulled heads off to check the gaskets and gaskets are like new still and the head i doubt is cracked since i just had them done..when a head cracks is normal to fill up all four cylinders? but i noticed when i pulled the gasket off it didnt stick to the block or head so im thinking of a sealing problem?? any ideas? im taking the head to get checked on monday just to make sure and its sbc also?

head gasket seal?

Sounds like you didn't dope your head bolts with Teflon pipe dope. People use different sealers to do it, but Teflon pipe dope is more trustworthy when it comes to re-torquing.. Did you re-torque?. Because you should. We do it at least twice after it has heat cycled. I know the lower row of bolts are tough, we usually use temp manifolds upside down no gaskets three bolts lightly snugged for quick removal...
By the way you wouldn't have to remove the heads to re dope and re-torque...... Duntov

PS, I really doubt you have a cracked head. If you didn't dope your head bolts it is almost a guarantee that you will have milky oil over the winter. We also use a copper seal spray on our gaskets; let it dry and re-coat a couple of times for insurance. Reason I mentioned the teflon stuff is that it doesn't completely harden, and therefore doesn't ball up in the threads like silicone when you re-torque after it's been hot, even a week later. If you had a cracked head it would likely flood one cylinder and not your oil necessarily.

You're not in trouble Duntov
