hand sanding AFR heads?? i was just thinking about smoothing out the CNC lines in the AFR heads i have, maybe. i would imagine it would be best to take the valve out and do it that way but i dont have a valve spring removal tool so i cant do that and i really wont wanna mess with it.
would it be a good idea to hand sand in there as far as i can reach, then clean it out really good? if so what grit paper should i use, if not then i wont touch them lol. i just wanna smooth the lines out some
tony if you read this let me know what you think?

Naw forget about doing that by hand and with the valves in. You will never get all the grit out with the valves in, and the bowl area that you can't get to is the most important. Also consider that you have 16 of these ports with about 10 different surfaces on each to smooth = 160 things to smooth! You won't last through all that doing it by hand. It's bad enough with a good air die grinder.
A NAPA spring tool is only about $10 and a die grinder $30; get the tools and do it right.

The CNC program we run has extremely fine "stepover" levels. Minimal airflow is found near the outer edges of the ports anyway (boundary layer of air is what this is referred to).
All your doing is taking a chance of slightly messing up the countours I spent so much time designing....especially in the short turn area where you will find it might be difficult to get at.
The 205 heads on my own car are just the way the came right off the CNC.
Find a better outlet of the energy you want to spend "romancing"....smoothing the CNC marks will net you nothing and there is risk involved if not done correctly.
Enjoy the new heads...
