Header gaskets

[95BLKGT5.0]

Are the copper header gaskets that come with Mac headers good to use.
I'm installing my LT headers and am wondering if there any good. I would like to finish the job today but all the parts stores are closed I think! I just have the copper ones.

The coppers are ok, the composite ones that come with some MAC shorties were crap.
