vacuum question

I am hooking up this Thunder series Eddy and I was wondering if it would be better to hook the dist. to the manifold vacuum port on this carb. instead of the timed vacuum port. my Duster has it into the timed port but didn't know if it would be better the other way. the only other vacuum I need to hook up is to the vacuum canister and I guess I will hook it that to the other line here. thanks for the info,Bill
