Holley jet ?

I have a 750 dP on my 360 we removed the choke flap
To get the extra power not overly experienced with carbs but
Learning so hears what I got the 360 has a large cam duration
And makes about 475hp the carb primary jet are#69 and have
A # 26 squirter the secondary jets are #80 with a#31:banghead: Squirter
So when I start the car I t runs rough till it heats up and it seems
To love the #80 jet when my foot is in it but it doesn't want to
Run when it's cold so is it the lack of choke flap or should I go bigger
Or smaller on.primary jet and or squirter. Thanks for replies
