does anyone know anything about these heads

[jdscofield]

i just pulled the valve covers off my 400.  the casting number is 7979007. never heard of them nor can i find any info on them.  If anyone knows anything about them, could you please give me the specs.  I'm going to guess they are probably crap heads cuz thats the kind of luck i have.
