Scott sorry to see your issues with the new build. You are one of the most driven guys I know and that drive will get you past this hiccup and back to the track in no-time. Thoroughly check the pistons to make sure you don't have a pinched ring in all the effected cylinders. When my Son Matt broke a small piece of a valve off it pinched a ring on the other side of the block. Good-luck and great job of getting it apart and on its way back again so quickly.
