Howards Cams Hydraulic Flat Tappet Camshafts - 255 int./261 exh. Advertised Duration
I would think Howard or Lunati Voodoo much better than 256-260-268 comp

you can compare with the Howard chevy version at that mid 250s duration below

even268 comp only has .454 lift and in a stock compression motor the Lunati or Howard should be better everywhere
note how the bigger lifter helps a lot more than 1.6 rockers as shown by the ford numbers
