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

Amen for that. Never disappointed Sns. I actually have received mail which mailman had marked "S&S" my middle name. 8)
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.
