SBC 400 headgaskets ???'s

[dickeymoore]

I have some Felpro 1014 headgaskets for a SBC 400 engine and the only thing is that one is a older version which is like a grey in color and the newer one is like a blue in color PermaTorque, will these gaskets work the same when installed on my sbc 400 engine or should I but another newer one?THANKS

Should work fine, just different colors.
