Mopar 340-J heads full port/polish

"Stock" heads can get you faster than that, watch g stock sometime where they're runni g 10.8's and 11's , fwiw.
How about pictures of the port work done?
All it takes is $, right? I’ve described them the best I can. If it isn’t enough info for you I apologize. Port work on assembled heads is hard to capture with the camera but I’ll try.
