One of the problems you will typically find is that people will go from unported to ported and also change other components like the camshaft. It's very hard to find a person that has data where the only change was going to ported. You might possibly find some info in a magazine test
Dwayne at PRH, Brian IMM, Radar, Brett Miller, pittsburghracer are all solid guys that do good porting. Most of them will port to the application. Big numbers are great if you are actually using them. No sense in having a big number at 600 lift if the cam is only 550... Lots of time the lower range suffers a bit when the high end numbers are big. There are trade off all along the flow ladder.
