Id these valve cover breathers

Guys, got this pic from another forum.

Can anyone tell me about the breathers on the valve cover. Who made em, and is something like them available today.

Thanks in advance

 

T, Offy made some small breathers part #3661 JR.

They are 2" wide x 1 1/4" tall and 20 years ago retailed for $16.33.

Stovebolt, that's a big ten-four on those being Offenhauser breathers. They look good and have the name cast into the cap. I bought a pair recently, for a cool and relaxed hundred bucks. At fifty a throw, they weren't a whole lot more than brand new Moon breathers. The seller had used them on some racing effort years back.

I wanted to use them to get some more summer wind blowing through my SBF. I was ready to grind off some fins on sweet old Edelbrock VCs to get a flat mounting spot. Instead I found some butt-ugly cast MoFoCo smooth VCs, and I figure I'll just pepper new Moon breathers on those clean surfacesssssss and save both the nice Edelbrocks and the Offy breathers for another project.

It just so happens I have another project with an SBF in it.

 

Thanks Mark, cheers. Chasing some down. What are the round ones BTW?

 

Hot Heads has both the full size and small ones on their website.

 

Sorry T, no can do on that one

 

They look close to Stellings (sp?) air cleaners.
