Default Re: 5.5 Head Spark Advance

I have the centrifugal advice in my car so I don't have mess with my spark control, but
my car does run cooler with the 5.5 head. Here in Florida we are seeing the high 90's degree and an occasional 100 degrees. My Moto Meter shows about 1/4 red on the road @ 45 to 55 MPH and just showing red @ speeds below 45 MPH. Love it.
