Walking through the shop I caught a glimpse of one of the techs installing the new GReddy big bore head gaskets.
Here are a few shots of the new head gasket being mounted on our 4.3L block.
If you look closely, you can see a stopper type center layer that GReddy gaskets feature to completely seal the cylinder by adding extra torque around each cylinder.
You’ll notice the outer layers are coated with a thin layer of nitrile rubber to ensure good seal to the head and deck surface.
