I was between these and copper/aluminum gaskets, the deciding factor was port dimensions. When using basic round headers on square port big block check heads (1974 454 in my case) the 5911 gasket is the single best fit to adapt the two shapes. They sealed great, but dont expect to re-use them, once the get compressed, they typically leaked if you remove the header and try to re-use these. Also, with these you can cheat with some permatex ultra copper silicone.
