LA 360 budget build ideas

I've been trying to research as much as I can on performance modifications. I'm understanding that port velocity is important for throttle response and low to midrange torque?So my question is since I'm not looking for high horsepower would 1.780" intake valve's and 1.600" exhaust valve's give good port velocity in stock 360 heads?

maybe under 2000 rpm at the most 2500 rpm, but I think your over thinking this. Most mild builds cam porting bigger carbs etc.. will make more torque from 2500 rpm and up, might be small loss 2500 rpm and under but probably nothing you can feel. There's not much you can do to add under 2500 rpm other than CR and or displacement. Maybe super tuned intake and headers and cam with no regarded for above 2500 rpm. For a daily driver type street engine goals to me is to extend the power and rpm range much as sensibly possible with out altering the under 3000 rpm much or at all, especially if low stall and high gears and heavy car.

The valve is the most restrictive part of the port why restrict it more ?
the rest of the intake tract will be the same size can't see it changing the velocity much or at all. yes you don't want ported W9 with a dominator or two on a mild 360 but can't see how something like 750 eddy heads, intake and a mild 215 ish cam is gonna make much noticeable difference under 3000 rpm.
