J/X Head exhaust flow?

Excellent. Thanks great info. Still it would be nice to take my heads to get flow numbers after I've done my porting just to see where I'm at, and use this info to help buy a cam. Probably overthinking it for a street car. But I do geek out a bit on stuff like this. lol.
Great numbers are a catch 22. Knowing where the port peaks in flow is key to a cam.
