You have a bad head gasket...

if its actually in the cylinders its a head gasket or warped/cracked head. This motor was more prone to develop a cracked head than older sbc's

Bob Beaman

If the intake has coolant running through it the possibility exists that the intake or it's gaskets are the problem. Otherwise the head gasket, cylinder head or block have issues. It is possible to get coolant in the oil with a bad head gasket even when the compression test comes out good.

Andrew Olsen

It's not possible to have significant amounts of coolant into the cylinders with an intake gasket leak. When they go "which its a common problem" they dump coolant into the oil. It doesn't get into the cylinders
