Things need break in time, my used part rebuild (other than all new seals) had 12inhg at idle, now it makes 18-20 at idle, it idles around 750-850rpm. Just give it time, and the pulley set up is a Gilmer drive.

ok, well how do u get that good of milage its costing me like 20 bucks a day to to drive like 5 miles back and forth from work, well and i think vaccume might increst becasuse i see like -10 vac at idle cold and like 13-14 worm after its wormed up and ive goten on boost a few times. hmmk. Yes its a gilmer drive pully set u can get them at www.tweakit.com and they have to be shiped from austraila and there super spendy but worth every penny i keep geting asked if i have a supercharger under the hood :-) ok well anyways i have apx just over 2k miles on my engine runs super strong never died on me its flooded 2x's and its always started right back up. I babbyed the engine (noboost) for the 1st 1200 miles. how long untill its broken in there atkins seals and ive herd atkins seals seat fast.

Should be basically broken in at 2000 miles... I've gotta say, you really suck at spelling man. No offense, but I just had to say it.

Either way, I'm guessing series 4, 8.5:1 rotors and it's street-ported? Either way, those vac. numbers (warm) aren't that bad. You should at least compression test the engine to know if there's a problem or not.
