Will these work in a Twin Cam?  Looking for rockers with a 1.69 or 1.70 ratio any suggestions ?   Any and all input is welcome, have a S&S 585ES cam in a 110 heads are ported with 1.9/1.6 valves and set to 600 lift, looking to increase the lift and the  1.725 ratio is to much.  Thanks Bob

What every one is telling you is Ultima metallurgy is unpredictable and very poor. Not even suitable for a budget build.

Those were touted/used at on time by a "shop", claiming that those would allow the engine to be more powerful than a speeding locomotive, and able to leap tall buildings in a single bound.
That proved to be quite incorrect.
