what motor? what are the stock ports like? what size are they? what port velocity are you after (to determine port diameter)? are there any restriction in the port? are they there for a reason?
how much boost are you going to run, how often will it be boosting, what rpm range are you using the motor in, at maximum, and also, most often.
what will be connected to the ports? what size manifolds/length of manifolds etc?
there are a milion and one things you need to know before porting, as it is part of a total package.
if there was an easy answer, then everyone would know it..
for zample, compare the big and small port 4AG heads, small port is good for NA because of higher port velocity, big port is better for high boost, because it has imilar port velocity with that extra boost, but will not be great off boost...
all depends, and then it is only an educated guess until various combinations go on the engine dyno.
