OK, so I put the new battery in, the diode test shows the alternator is fine. I tried both a chrome box and orange box, same idle conditions using both boxes. I got the best idle highest vacuum with the mixture screws out 2 turns. The idle is better but not great still. I didn't have a helper today but I opened the rod covers and for the most part the rods stay down and don't bounce while in Park but when the idle takes a dip and idles down they bounce a little. I can rev it a little and they instantly come up as you would expect. I stretched the springs a little to make them longer and it did help some by doing that but I feel the idle could be more consistent. What do you all think now?
