Looks like a nice gasket set for my LS build. One thing to note is the valve cover gasket in the picture doesn't look right but the gaskets that came in my kit are molded in the correct shape for LS valve covers. I would recommend if you are doing an LS build.

Used these on my Caprice police car. It has the L77 and it seemed to all line up. At minimum the car is up and running fine. Quality seemed good.
