BLOWN BBC setup

Stephen,
What closed chamber head do you use? Do you know if the top running fuel Chevy big blocks in the 1970's, such as Valley Fever, Zeller, and Rodac, were running closed chamber heads as well? What do you do to hold the head gasket?

Thanks!
Michael D.

 

Michael,
We like the 840's the best because you can get a better spark plug for them, but we also use the 291's. I don't know what those other guys were running. We put a O ring in the head and a receiver in the block. We are going to the PRI show next week is anyone from this site going ?

Thanks
Stephen McClain
