360 LA installing Promaxx Aluminum heads

It's a 625.

That 78 secondary jet was the smallest in the kit. You thinking I should step it down one more to 76 to lean out WOT?
What TT5.9 said. Not to repeat, but add in….
Aim for that 14.6 @ idle. While your driving down the road, it can be a little leaner. It’ll work for mileage.
The secondary side is rich. That AF is fat. But your getting close. The drag strip should be used for the secondary side once that primary is dialed in. Your right on the edge.
On the power enrichment, I don’t know what the color codes are. IF you have a vacuum gauge to run inside the car, you can watch what it does vs your gas pedal position and what your doing to help get it where it needs to be.
(You are using a vacuum gauge to tune this right?)
If it were mine I would lean out the idle and tip in, idle 14.5ish, tip in 14.5-15.0 up to the point of power enrichment, then aim for around 12.5ish at WOT. You’ll likely see the best power at 12.2-12.8 WOT.
