Gary, the aluminum should do a better job of cooling for you overall.

On my Kitfox one, 582 engine, temps were a bit high as well. Lowered radiator about 1". That lowered temps at least 15 degrees. Then I checked the gauge and found it was reading 20 degrees high. Could have left things alone if I had known. These are the same radiator cooling 100 or more HP Rotaxes. JImChuk

Also you could change the mixture, I fly with 70 (water):30 mixture.....
