BBc ALUM head 111579

[EZ Nova]

Does ANYONE know anything about these heads? I seen a set for sale but can't find any info on them. They have snowflake AND bowtie emblem on them. I'm thinking old BOW TIE heads???

Thanks, John

Can you show a photo of the emblems on the heads ? Yenko had some cast in the late 70's and early 80s. I have some info on them in my archives.

This is what I got. As you can see, there is a BOW TIE on the RH exh port and a SM snowflake on the LH exh port. you can see the "579" on the 4th valve from the right. I'm thinking EARLY GM BOW TIE??? Thanks John
