Just wanted to run something by the race / hi-perf guys. I have some CNC ported 2nd gen Edelbrock heads. At this point I am doing a port match, and found something that isn't sitting right with me. Keep in mind that these were ported around 7 years ago, and I won't be able to gripe about them, so they are what they are..

Port sizes are (Round Numbers) 1.48 Wide x 2.580 High
When getting the gasket to best match the head ports, I had approx .050" of material on both the top and bottom. The thing that is not sitting right is the bottom being .050" larger. Isn't that a dead area? Wondering if they just weren't done correctly or if they used more flow bench vacuum to get better numbers which would not be beneficial in reality. Going to proceed and cut the intake about .030" smaller, but what do you guys think about these numbers on the port size?
