Any Power from Porting???

[Blaster]

I am seriously contemplating getting my edelbrock 6037's ported and polished over the winter, nothing too crazy though because it is a daily driver for half the year, it it worth doing?? My buddy says it will produce the same amount of gain yet again as when I put the heads on originally. What could I expect for gains, or should I just leave the poor heads alone??? I would really like to get rid of a few tenths in the 1/4. I've got the total edelbrock power package except for a bigger mass air meter done to my engine.
