LS MARINE ENGINE CONVERSION: GM LS 4.8, 5.3, 6.0, 6.2 Installing the Headers

369

Now’s the time to install our Headers. We have a set of silver powdercoated wet LS headers from Lightning. Because we decided on a (much maligned) carbureted application, these headers won’t need to have an O2 sensor provision that an EFI application would have. Follow along as we install the headers on the engine and install the water tree and lines to the thermostat housing.
