If what you're doing is modifying a GR block, then I'd recommend  
starting with "how to write a block", copying the source you want to  
modify into the gr-howto directory structure, modifying it there, and  
installing it from there.  While it doesn't get referenced in the  
same manner in Python ("howto.blah" instead of "gr.blah"), (re) 
compiling is very fast and it really is quite simple to move between  
"howto" and "gr" in Python.  Admittedly it's been a while since I  
looked at "howto", but I'm sure it will work for this case (modifying  
existing gnuradio-core GR blocks).

OTOH, for modifying other GR stuff that is in .cpp, there really  
isn't a good way around just using the source in gnuradio-core.  Good  
luck! - MLD
