[6pack] Get into my Head

[peterschop at aol.com]

OK, what is a Circle B head?




So some background.  I have a 1970. The head is a Circle B with the narrow 
ports.  I am not going to change this.  On a very good price, I picked up a 
second Circle B with the narrow ports.  at least for now. I will 
have my head milled to raise compression to 9.5:1.
