Yup, now you are getting the picture. Find a old junk SBC head to practice a bit.

Porting with the stock 1.84" valve will improve flow for sure but porting + the larger 1.94" valve (with a new valve job) will make more flow, cause the valve is just bigger.

The 1.94x 1.60 valve combo is for a ported 305 head on a 350 motor.

The modded (cam etc) 305's power band is going to be much higher rpm than the stock motor.
It wants to rev. (Gears, converter) with 35" tires you will need some serious gears. It will be lame with the wrong gears.
A hot rodded 305 SBC becomes just as much as a high rever as a 302SBC is famous for. wants serious gears to perform/
The long stroke has nothing to do with it.

If your headers are "zoomies" convert/modify to a long tube style with collectors. ( more power/more torque)
