I don't have enough info to make a great guess. Where there bubbles in the radiator? What level did the radiator drain to just sitting? I ask because the head gaskets are lower than intake. Either way, I would blow air in the cylinder I know is leaking and see where it comes out. I dig the Blazer how it sits, the patina is cool. You should paint your logo on the doors like old school shop trucks. I'm going to challenge you to name it.

After Further investigating we believe its a blowed head gasket definitely mixing with the oil and blows out radiator. Part 2 is coming soon will be removing heads.

Blows out the radiator is a sure sign it's a head gasket. The compression stroke is leaking through the head gasket, it wouldn't do that through the intake gasket, it would just suck it in. Milky oil could be from either gasket. I had a '96 Suburban with that engine, I don't recall it having aluminum heads, I don't think it did. "The Cylinder Head Shop" in WV has those heads for $499 a set shipped - should you need heads and don't have a compatible used one.. I've used them often, great quality and service. It would be nice just to do the gaskets and not need anything else. I always end up grinding valves at a minimum. @@bensautorepair9914
