• Exhaust Ports

• Chamber

The intake ports just got the typical treatment you would include in any intake porting job.  

• The bowl transitions were pretty poor as cast so I cleaned them up.  The transition from the throat of the seat to the bowl are now smooth and almost the same size. 
• The entire rough cast port surface was smoothed with cartridge rolls.
• Some little bumps hear and there were removed if small enough and smoothed if the couldn't be completely removed.
• The back side of the guide boss was dramatically reduced.  (Some people say you can eliminate the back side of the guide boss completely.)
• The front side the guide boss was smoothed.  It MIGHT be worth shaping it into a fin to direct flow, but looking at the these awesome intake ports it just didn't seem necessary. 

The only thing keeping these ports from being a straight shot is the curve around the push rod hole.  It is just too big to remove.
