Sbc head gasket issue

[78broncoboy]

So my 1975 GMC with a 350 is leaking coolant into the exhaust on the driver's side. What are the chances it's a intake gasket issue vs a head gasket? No mixing of the oil and coolant, and no combustion gases into the coolant. It's a rebuilt engine not sure of mileage, but no excessive oil use or blowby. Just trying to plan how far I'll have to tear it down to repair.

Anybodies guess honestly. Grab a set of gaskets and tear it apart. Pre spray the exhaust manifold bolts/studs with WD-40 or the like. If it runs ok besides loosing coolant (check everything out) you can put new head gaskets on it an ride in a Saturday.
