port & flow head

[dempsey400]

How much differance will porting and flowing the head make on my 406? I have a e-series exhaust, stage 1 hotcam and a ross 10.6 to 1 piston. A friend is doing it .

i recently ported my 440 with a bigger carb and it made a huge difference. you should feel a difference to if its done right. i had mine done by Bernal Racing.
