oh god... oil in the coolant.
well, i'm just finishing up swapping heads on my ls1 car, and noticed today that there was a little oil in the coolant. is there a possibility this is just trash that was in the heads getting into the cooling system? the heads had oil in them, so i'm thinking it might have just mixed in with the coolant when i put them on. i took my time on the head gaskets/ heads. i torqued them down to spec, in the order that was specified. also used all new gm performance multilayer steel head gaskets, and head studs. oil isnt milky, and no white smoke from the exhaust either from what i can tell. i really hope it isnt time to pull the heads off again before i even got the car running this time.

Did you change the oil after you swapped heads? If not you need to ASAP!!! When you tear heads off its impossible to not get coolant in the oil. So if you haven't changed the oil since the head swap that's normal and it needs to e changed.
If you changed the oil AFTER the head swap and now have coolant in the oil it's possible something got messed up along the way.

Flush the cooling system completely. Refill, run the car, then see if you have any oil in it.
I would guess it is residual that got into the cooling system.
And you are saying you haven't taken the car above 4000 rpm, not that the car won't go over 4000 rpm right.
