Yes and no. Get the tang showing in the injection pump port with the crank timing at 14 degees past top dead centre I believe on these engines but check in the archives. . If the tang is not there turn the engine over one more turn with the injection pump moving along as well. If tang in injection port is now visable. Then get the number one cylinder valves pointing upwards more or less at a 45 degree angle for each lobe. Crank back at zero. Using the closest way to get it there.

Position head and install cam sprocket. If tang is not visable in either senario you have lost the injection pump timing so just get the head and crank marks right. With the number one cylinder valves again generally pointing upward. Get a locking device.

Set the crank at the fourteen degrees. Back the injection pump out and get the tang locked down. Then reinsert the injection pump and you should be timed properly.
