Holley 800 cfm MODS

my carb is a holley 800 cfm, list # 4780-5

i bought the shiny finish holy main body : http://store.summitracing.com/partde...5&autoview=sku

im rebuilding the carb right now.

i have a question,

the Primary jets in my carb are 78 & the secondary jets are 80
my carb is equipped with a 30 cc primary pump & a 50 cc secondary pump


Im going to have two power valves in the carb & the main body came with 72 Pri-jets & 84 Sec-jets
which jets should i install?

should i leave the 78 pri-jets in and change the sec-jets from 80 to 84?
