First time Holley tuning help

I haven't checked vac at idle in gear. In park it is 10-11 in hg. I have power valve plugs if that would make it easier to tune since it is a just going to be used at the track. Pvc is from rocker cover to intake manifold where the brake booster line normally goes. Current power valve is a 6.5 from a trick kit. Carb is an 1850-2
