Would be great to see what you would do with yours. Good suggestion re bringing the exh port tunnels forward some more. I'll probably leave that until next time, but depending on how I feel I may crack it now.

I had no desire to increase the size of the main exhaust port any more than required to match the spigot. Some material had to be removed during the process. No intent to make it any bigger.

Quick question - how does the relationship between port window (in cylinder) vs port volume influence engine performance? Thats before you start to bring angles into the equation.
