What a difference. The upgrade took most of the week in between work and such. New intake (air gap), shorty headers, needle & seat and fuel reg, Plus a bunch of other support stuff. I scannned the temp and now (at operating temps) it is 154 degrees, over 200 degrees lower. The valve and seat was super easy when it was on the bench. Fuel pressure is set at 4psi, down from almost 7psi.
