Been working on a pair of these Edelbrock heads off and on for awhile. These started life as a Chapman CNC port that I revised on the intake side cause I felt it was lacking, ended up gaining 35 cfm! Put some epoxy in a few different areas after trying to figure the port out, these are pry worthy of a CNC program for their size.

It turned out decent, I may tweek it some more. I'm doing this set for a motor of mine just need to finish the other ports first. I was thinking about sending them out to get digitized.
