Guys,

I built a complete roller rocker assy with stands and a 1.0" shaft, rifle drilled for oiling. The ratio is 1.85:1. After 20 pulls on the dyno the valve lash didn't move.

If someone will explain how I post pictures I'll show what I built.

By the way, I talked to Vizard about headers for the GMC and he didn't think his experience with the 4 cylinder would apply to the inline 6 engines with siamese ports.
