Typically no because head gaskets usually go because of high mileage or overheating, if intake had coolant traveling thru some ports and reassembly allowed leakage or coolant line/hose attachments on it and they leaked then low coolant could cause overheating and damage head gasket but there should have been a warning of some sort to the driver with low coolant warning light, high engine temp light or temp gauge reading high that you should have caught and shut down engine before damage. May have just been a coincidence also but would need disassembly to inspect for source.
