Default Re: Stocker Cylinder Heads....

In the 1970s Racing Head Service and others collected dozens of heads and selected the best ones for Stock. There aren't many of these heads left today and it is "amazing" how well they flow, all of them, not just the 5-10% that RHS found. The 11th Commandment: "Thou shalt not get caught." lol.
