 Mark Stevens did the work.
 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.

 I am using all stock tin and oil cooling, no external oil coolers.  I also
use synthetic oil.
