What brake pads to use for Kelsey-Hayes setup?

I have a 67 Barracuda 6 banger with a stock Kelsey-Hayes power front disc brake setup with 10" rear drums. It doesn't stop all that great, seems like the fronts are not grabbing like they should but they're way better than the original 9" drums. I now realize I need something that actually stops! BTW, the pedal feels good and is near the top so I don't think bleeding is the problem. I thought I'd try something other than cheap pads I started with so I am open to suggestions.
