wanted to buy 915 or 516 mildly ported heads

if you have a stock engine with decent flowing heads from the factory and then take the stock heads and mildly port them. then put them on the same stock engine will there be a HP gain and or will the peak TQ and HP move to a higher rpm.

not sure why the flow went bad after .300 lift. the stock intake valve was 1.87 new one 1.94. want to get another 10 cfm after .300 lift. with a stock intake valve on stock heads they make 190 cfm at .500 lift.
