well keep searchin and saw 20v of 210hp so i think in the video are the high comp 4age 16v and 20v too

in the bill sherwood he says the small port (16v)is the best option to 200hp but the formula atlantic is big port

so he says for more 200hp the big port is the choice but
my issue is if the head is big port and the engine oviusly has no turbo how the hell will get more air ,the depression of the piston makes an air flow
to the combustion chamber if the port is small thats better in high revs increase the air flow and morepower but if like the 4age atlantic has big port the depresion of the piston sucks air to the chamber but in high revs still gets the air flow velocity a big port so i dont understand

the piston sucks the air normal ,smallport less air ?big port more air?
but how the small port make 210hp well i think for the small port increase the air flow in high revs but the big port sucks more air than the small port cause is big port?
