How To Replace The Head Gasket and Intake Manifold Gaskets On A GM 3800 Engine

Here is a link to a kit similar to the one I used in this video for any ~95-05 GM 3.8/3.4/3.2 motor:

In this walkthrough I replace the head gaskets, upper intake manifold (UIM) gaskets, and lower intake manifold (LIM) gaskets on a 1997 pontiac bonneville.  These steps will be identical for almost any GM 3800 / 3400 / 3100 series II motor.  

If you have any questions feel free to post them on the video and I'll do my best to try to help!

Here is a link to the the text walkthrough I used as a guide for making this video:
