Cam lobes color

I was doing valve covers and noticed I don’t have a even color on my cams seems like I’m running lean also on my front carb I’ve already done carb swap from dual webers to su intake gaskets. With the color tune I could never get the front carb to get a rich condition and seems to be running lean still. Compression was 150 on all cylinders five or take 2-3 psi. Values have been adjusted
