B16a cylinderhead development pt12




here's  a picture of all 4 intake ports done and textured
-ready for machine work i.e. competition 3 angle valvejob and deck resurfacing
- to ensure  superior headgasket sealing/longevity and OEM valve seals installed



a closer shot of the ports  to show the texture  it has developed into

*it is not smooth  nor very rough, just a fine balance in texture
  where it creates  ideal surface tension to keep fuel into suspension
  and improve  overall flow

* the term "port and polish" is a misnomer , as you dont really polish anything
 but keep the right texture

 on the exhaust yes, you can polish it as mirror finish as you'd likee
 but after a few minutes of idling, let alone  driving...  it will be coverd in carbon byproducts , so texturing the port and keeping the shape uniform and sleek
 is a more important  goal to be set  :)

*so if you hear someone say  they will polish the exhaust  and the intakes not so polished,   slowly and kindly walk away...  as you know  your cylinderhead might end up being a gas guzzler  he he he
