Holley Carb/squirters+jets ?

I would start with stock pv because that 1 is too big for your combo.
Set timing to 35 degrees all in by 2500 rpm.
Make a base run at track.Jet up 2 sizes primary & secondary & make another run.if mph goes down jet down 1 size primary/secondary.check mph again.Repeat until you get highest mph,then reset base carb settings.
I thought my car was running lean until I put it on a chassis dyno & found I had a/f ratio of 11.5 (rich)I was running stock jetting on 850 vac Demon.After a ton of runs & several rd tests.I wound up at 83/85
jetting & a/f ratio of 12.9 straight across.BTW picked up 27rwhp/23ftlb
just from leaning out car.
