273 commando Build

tmm.
I received the 273 commando head gaskets today #2463 338 , far and behold they are not what people say they aim to be. p/n 2463 338" Is NOT a steel head gasket , it's composite . the bore is not 3.63 it is 4.0 and the thickness is not .021 it's .041. I think there never was a steel head gasket produced for the 273 . first of all >>>>>>>>>>>> #2463 338 is a composite gasket not steel Here is a quote >
General Information
Near impossible to find a set of Original {.020"} Thin-Steel Head Gaskets {#2463 338} for the 273 4-Barrel.
they used on the 2bbl as well. That's what they used back then.
I DON'T THINK SO !
