You should see good bottom and mid range power improvements.

Its a good start. I keep repeating myself but if you want to learn about porting get some books and at least learn about how to calculate what the effects should be, otherwise you'll be just like most others talking and not having a clue. The templates are a good start but there is alot more you could due if bottom end is your goal, as far as porting goes.

you can go larger on those finger ports. Also, do a little epoxy work to get a better flow rather than just a "mash" of air.
