RE: heads
+1 depends on the rest of the engine
Cam? Carby? Exhaust?
as a guide, if you want more power your best bet is improving the whole engine. More $ should mean more power!!
If you just do one thing like porting the heads or putting a bigger cam in or a big carby in isolation, you will usually be disappointed.
I bought a set of heads from a guy who had done just that and lost power and streetability by going too big for the rest of the engine. I dont understand the mechanics of why, but it just doesnt work!
I say leave it alone unless you are going to improve the whole package.

RE: heads
You'll feel the difference. I wouldn't say it's worth tearing an engine down in order to do it though. And grinding on the heads with them on the block can be done, but adds a bit of risk with metal shavings getting wear you don't want them...kinda like sand when on a beach.
