Hi TronX,
Yes, the spacers come with it. O'Reillys is an auto parts output just like AutoZone and others. I usually buy FelPro gaskets. They seems to be the best headgaskets to hold the old Vegas, especially after they were sleeved. I would believe you could get FelPro brand at most places. The Fordonline.com would be good too, but depends if you can wait a few days and pay shipping on top of that price.. Good Luck, Duane in KC
