Crankcase Ventilation

You have a ring problem! I have never used any crankcase evac on my drag car and have never had any problems. At WOT the most vacuum you will ever pull will be 1.5" with your four barrel so a pcv valve won't help much. An exhaust pan-evac will help a little more and a vacuum pump will do the most. I would check for a broken ring or an oblonged cylinder bore.
