thanks , right now it seems to be good,I may have to change it back this summer,but there is plenty of cold air right now around here.

would cooling my fuel have the same effect ( more btu per unit of volume) and help any .

I,m thinking of adding an electric fan under the hood in addition to my stock belt drive fan this summer to help with the heat from the header.

oh what a feeling:
