318 head porting for the average joe

exhaust port progress, numbers come tomorrow..

u can completely rid the roof of the speed bumps like done below, then round the bowl and leave the slightest lil micro bell shape to the seat on the far side and blend the guide & bowl roof out to the window..then straight up off the seat and rolled a lil back at the top for the ssr.
These are just in the process and rough cut, not quite done yet.
