I've seen the pictures in the porting section. I have some questions though, we are
starting to port some 66' 289 heads with the
air injection holes. Once we plug the holes it looks like we might port through the plugs. Does this sound right? The pictures I've seen don't show the heads with actual air injection holes just the bumps. Any pics out there????
