My Dart Swinger Project!

Ok thank you for the advice! Much appreciated! Does the area around the valve guides look ok to you or should I go farther?
Need to smooth it out, get rid of the choppy look.

I use this to start with... when they get smaller from use, then you can use them for the harder places to reach, like around the valve guides. I use the sand roll, then a buffer (but only buff the exhaust side). It takes me about seven hours to port 1 head
