318 driver - cam change or not?

I would go with this cam if you do not mind the aggressive rate of lift
Howards Cams Hydraulic Flat Tappet Camshafts 711381-10
or this one if you do
Lunati Voodoo Camshafts 10200700
and these springs with either one
Trick Flow® by PAC Racing Single Valve Springs TFS-16901-16
and it would gain some power for sure.,As far as break in just make sure to use the tried and true parts you have (ignition/carb) and I would recommend a dedicated oil such as brad penn etc.
