Ron that surprises me on the modified exhaust port shown in your book, I thought for sure it would show better flow than the results, good information.

Tim these are the pictures I have, the first ones shows where the cut was and if you need the floor of the port thickness I can get that for you. The machining on the intake ports shown in the picture was an idea for a fuel injection setup that didn't happen.
