Several folks, including DennyW, have told me that adding 1.6 ratio rockers to ONLY the exhaust valves helps a lot with torque. At first I thought if any, the 1.6 rockers should be on the intake valves, but now three people have told me to put them on the exhaust valves including a circle track racer. Anyway when the dyno results start coming in we should compare to some of the many results given on Ryan's site:

In particular, Ryan's example 56 shows this effect. The improvement is most pronounced for short duration cams like the stock cam so it would be interesting to see what happens to a mildly modified 350.
