B16a cylinderhead development pt.3





a shot of the ports, viewing from the chamber side

the lighting indeed helps to show the texture of the port surface
for better fuel atomization

and how it changes in texture as it reaches the throat and to the seat

-in theory this is to speed up flow as it reaches the valve
 with attempts at generating more possible flow and intake charge
 into the combustion chamber

- the section between guide boss and splitter is noticeable here
  with regards to work done to minimize obstruction in flow

- guide boss itself is seen here having more "aerodynamic" profile/shape




another shot from the chamber viewing the intake ports

- here, a more visible guide boss  shaped with a more aerodynamic profile
  some chop it all off, some shorten it ,  but by shaping it this way
  you minimize volume increase and actually maintain a higher flowspeed

- notice the texture change of the port leading to the throat
  and the throat being concentric to the valve seat





another shot from the chamber side, this time showing both valve entry

- this was taken bfor being totally finished  as evidenced by the texture change
   but also best illustrates the work done to it,

- the keen eye may notice , the port itself is still pretty "mild" as far as port enlarging
  and or sizing goes ,
  but funny enough this head will promote good intake flow velocity
  thats good for making decent torque 

- this head could work on smaller displacements and do wonders with regards to
  torque and power production
  and still be able to work with larger displacements , with just changes in
  camshaft profile to match
