pretty good numbers. My old Eddy's just came back from a professional porter who just retired from a big name company. I got lucky to get his name. They also have the 2.08 intake. I ran them a couple years as ported by my local machinist. The new guy also did my S Victor. wish I had taken better pics, but it's all together now.
The flow sheet has the first column as ported locally. Column 2 is what the new guy did. Amazing numbers...especially mid lift. Keep in mind my bolt holes are tubed, and I run push rod oiling, so I think that explains a little.
All this preserving the short side as much as possible. He said most of the increase came from the roof and a different valve job.
