SB engine rebuilding got ya! School is Open!

Always clean your Deck & Head Surfaces before setting the Head Gaskets and the Heads. Any Oil from setting the pistons in the cylinders needs to be cleaned off all surfaces. Torque your heads correctly and in sequence.

Don't forget to put that RTV in the corners on the Pan & the Intake Gaskets before setting them to ensure a good seal and no leaks.

Use a little RTV or thread sealer on the Timing Cover/Water Pump bolt threads so there are no water leaks.
