What are those studs on the bottom right and bottom left of my engine block that you place the gasket on that hole it is place while so you then can place your valves on? I can't seem to find them on the engine I am going to rebuild for my truck. I am attaching a screen shot from your "how to build a" 5.3 LS - Part 8 series and circled the part. If it does not attach then let me know in your reply. It shown at 5:23 mark, bottom left of cylinder 1 or right of cylinder 7.

Those are guide studs for when you set the head gasket on the block. It prevents the gasket from moving.

It also goes into the head for it seating correctly.

Awesome. Just one thing. I can't find them anywhere. I tried Summit Racing and then just searched the internet, maybe I am not searching correctly. Can you point me in the right direction? It is a 2003 5.3 LS.

You can check with the dealer or any machine shop. They are common items.
