I need the torque specifications for the valve cover so I can put a new gasket in. Also does it need to be torqued down in a certain sequence? Thank you

Thanks for visiting 2CarPros.

Chevy does not specify a sequence on this. I recommend working from the center out in a criss cross pattern. Torque spec is 70.8lb in
