2007 6.0 High Pressure Oil Leak Diagnostics?

2 Months ago I had to replace My IPR valve and also Replace HPOP while I was at it. Last Week truck started fine cold but no start hot. I pulled it in and began the High Pressure oil system air test. I replaced 1 top O ring seal on an injector that was spitting air. I can still hear air leaks on both sides but cannot pin them down. HPOP is good, IPR valve good, Updated Stand pipes and dummy plugs all good. Leaks seem to be toward the rear of the Heads on both sides. I have tried every test that I know of and am coming here for any other suggestions. I have searched other threads and cannot find any other methods of detecting leak. Please help with any suggestions!!
