My Speedmaster offset rocker set look just like those , color wise. They are gonna be an experiment, since they were on sale at a quarter the price of Hughes, and $1000 less than HS. (I know, I know. Sometimes you get what you pay for.)
I ran comp stainless in my Cortina, they were bulletproof at the spring pressure I was running.. if I could find OFFSET stainless for Victor heads, I would buy them.
