I also had the valves unshrouded. I kept deck height stock at .85. The CR was set from that. I am running a Webcam cam with a small increases in lift and duration. Before the update kit and quad tip plugs, the temps were @275 to 350. After the kit update it ran @250 to 300. Now it runs 225 to 250 at 60 to 65 mph with the addition of the quad tip plugs.
