I normally use the timed vac port on the side of the metering block for the dizzy ,and the big port for your pcv valve ,which holley do you have,,and you are in the wrong section ,you may get a better response in the engine bit ,where in northants are you ,and I could take a look for you maybe

If you're buying a new Holley, the instructions should tell you which port does what, and where to hook things.
If its a used item, then google the model number found on the carb.
Can't really give any more advice without more information or pictures..
