Unless everything matches (heads, intake, carb, cam, exhaust, spark) you're just wasting $. A motor is only as strong as it's weakest "link".
When I was 18 I changed the cam, intake and carb on my 72 Chevelle. Guess what, it was slower when I was done. Should have dumped the money on heads (it already had headers). Oh well, live and learn.
Nine years laters, I made a better choice and just bought a crate motor from Summit to put in my 71 Vette. Never took it to the track, but she was pretty damn fast after that.
