Trying to help a friend with his valve adjustment on a 2.6. Never worked on a 2.6 before, but I've adjusted valves for the last 35years on various 911's that I have owned, and wondering if I can follow the same principle. Start at #1 TDC ON COMPRESSION, adjust #1, then rotate crank 120 degrees clockwise and continue to adjust in firing (162435) order (COLD)??

Is there any valve overlap that I need to be concerned about that is unique to this engine?
