Speaking of the rocker oiling system, I have been thinking that it might be an improvement to drill the second and forth rocker stands and connect them together with some small 1/8" copper tube so the oil from the fourth stand will also send oil to the second stand. The holes in the bottom of the rocker shaft are slightly larger to allow the oil to flow into the hollow shaft to oil the rockers. With this modification, I could use the studs without reducing the center diameter of them for the oiling?

What got me thinking about this, it the new Trick Flow head are supposed to re-route the rocker arm oiling so the oil does not flow between the intake port walls.
