Im currently building my motor and i wanted to know if i can block off these coolant lines or do they have to be joined together. Im not using the Heater and running an aftermarket oil cooler so i dont know what to do with these coolant lines.

the rear line feeds your turbo. if you are running a non water cooled turbo just plug them both. if you need to supply the turbo i would just use an adapter in the rear port and run it to the turbo and then just plug the front one.
