B16a cylinderhead development pt.5

Bigger now to show details of the exhaust port

and the lighting and shadows help visually
in showing the overal shape achieved

-notice the port's curve from valveseat to throat all the way to the exit
 the attempt is to shape it to achieve a gradual of a bend as possible
 without needing too much material removal , we avoid hogging out the ports

- the lighting shows this (roof section of the port) and the shadows  help
  visualize the blending on the splitter and short turn radius

next pic showing much of the same, but with more visible details

shadow and lighting doing its part in showing the overall port curve/bend and smoothness

- notice the casting marks on the throat (splitter side) still a little bit visible
  hogging it out isnt needed  unless you dislike torque :)
  even on the port exit at the outer perimeter the casting flash is a bit visible 

- notice at the base of the splitter (top of the splitter in the pic) some of the
  tiny dots are casting bubbles , no need to totally remove them
  as the only benefit we can get from that is cosmetic in nature
  and port volume increase isnt really needed here

this cylinderhead was done for a client
who has a simple build that is a b16a (1600cc)
on a 4door EK variant sedan

with these heads + decent cams and a good exhaust
it has run well into the 13second range in the 1/4mile
and thats with just a 1600cc displacement
