Hughes Engines 1.6 Rocker Geometry/Setup

Holy Mopar guru overload... LOL
My Hughes 1.6 rockers are great right out of the box... Only side to side shim's... Been running perfect for years...

One must wonder how these engines ever ran the first 40 years before geometry started getting corrected or even worried about it....
Nice! Your lucky, what heads are you running them on?
