I originally bought the Snyders 5.5 head and installed it. I was so impressed with the performance, better hill climbing, faster pickup, that I sold it and installed the Snyder 6.1.

I am very happy I changed it out. There was a noticeable difference from the 5.5 vs 6.1. Although not as noticeable a change as was the original 4.2 to 5.5 swap.

I can not imagine what a 7.1 head would be like. If someone made one that looked original i would go for it.
