This is what you need to modify very slightly.
This needs some modifying to fit right. this shows the top, side and underneath of the seal.
Hello!, and thanks for the advice........I've got a confession to make toward safety under the hood. I lost the tip of my "ring" finger to the turbo of 5.9 Cummins diesel. It was at work on Friday the thirteenth, of April 2012. It's a long story, but the finger is shorter. Now, back to the engine stuff. In the maintenance manual, it states to warm the engine up to operating temp, then set the valves. DON"T DO THAT. ALWAYS set the valves at room temp.(cold) You will get more consistent results this way, and not get burnt on hot parts. I do this a lot at work, so it's easier for me. Rule #2... take your time.....don't get in a rush, and when you set valves, get the same "feel" from each rocker, not some tighter, and some looser. Don't get frustrated, if it takes 10 minutes to set one valve, that's ok. Find #1 T.D.C., by watching the rockers on #6. When they BOTH start to move, you are at #1 TDC. Mark the crank pulley and the tip of the timing pointer. Now this I'm saying from memory, so remember that. Set the valves on #1., then the Intake on #2, and the exhaust on #3, and the Intake #4 and Exhaust #5. Mark them with something to show your work. NOW, roll the engine over ONE full turn, in the direction of engine rotation. The rockers on #1 will be moving this time. Set both valves on #6, and the rest that need setting. IF your rocker arm tips are badly worn, NOTHING you adjust them to will quiet them. You have to remove the rocker shaft, dress the rocker tips to a flat surface, BUT not go through the hard surface treatment, or they wear even faster. Then you will be setting to a true surface, not one with a recess in it, that fools you. The difference in how that engine will run will make you smile, trust me. As for the 5.9 Cummins valve seal, I THINK it's from a 5.9, I had put all the stray seals in a bag at work, from engines we do, but we send the heads out, so the seals just don't get used. I can give dimensions and better pictures if you want. I slightly modified the original pump piece, and did the rest to the seal, but it works fine. Would you guy's like me to do another carb, and show everything, now that I have something to work with? I have two more engines, and both need work on the carbs.
