Now that you mention that about the runners, James, it reminds me of an old post where you posted some pictures:

Looking to do the same thing to my manifold, since you've proven it works.

Curious how you removed the divider. Just roughed it out with a carbide burr from both sides?

Also curious about your head porting work. I figured the stock ports should produce some swirl, but apparently, they do not. 10 cfm is a nice gain though. Was that with a 3-angle valve job?
