It should be the same head as the Cleveland engine; Edelbrock 61607.

Maybe, but they got the rod length right in the 69 blueprint and the Accepted Parts list right. They have 289/BOSS 302 with 5.155 rods and 302 (Windsor) with 5.090 rods. I have a parts interchange book that supports the rod lengths I listed.
Should have read it cover to cover before I started this thing. Live and learn.
The BOSS 302 block is an accepted replacement for S/Stock. With the true BOSS (tunnel port?) heads hard to find, my guess is that NHRA approved the AFR head for BOSS 302 builds to allow access to the mechanical cam and big carb that was on the stock BOSS 302 in 69 and 70. You could build an almost BOSS 68 Mustang and run it in S/S, not GT.
But then that's too logical...
I'm currently researching everything I can find on the 68 Cougar to make sure the Holley carb they list isn't a typo. That's a 390 carb, and I need to verify that it was available on the 302 Windsor 68 Cougar.
Now I know why t here are so many bracket cars at the track these days. Just build it and race. Box or No Box. Nothing complicated like c.c. ing heads or micing a throttle bore.
