Haven’t received my parts as yet. Items have shipped and shipping was extremely fast!! Will update as soon as I receive the parts! Thnx ATL for the fast shipping!! Part arrived within 3 days! Haven’t had a chance to install them yet. Will update in a few weeks! Well now I have the heads installed and they seem to perform as they should. I have zero complaints with ATL Diesel! If anyone is curious I ordered a set of 3 Cummins N Celect Plus heads. The heads looked great! They are also performing flawlessly! Thnx ATL Diesel! 6 and half times cheaper than Cummins OEM heads!
