Default oil/coolant problem

What would cause oil/coolant mix in the intake valley?

Since the LT1 uses a dry intake (no coolant crossover), a bad head gasket would be a concern. Cracked/warped head or block could also cause coolant to appear in the oil.

I would lean towards the head gaskets. what does your oil look like on your dipstick / under your fill cap? have you overheated the car or wrecked it?
