Working on a 1962 Chevrolet 235 engine. I watched a Youtube video that explains you can put Cylinder #1 on TDC and then make the valve adjustments on Valve #s 1,2,3,5,7,9. Then put # 6 Cylinder on TDC and make adjustments on Valve #s 4,6,8, 10,11,12. I did #6 Cylinder TDC first and adjusted valves, now I've got Cylinder #1 TDC. Things worked fine for 6 TDC, but with Cylinder #1 on TDC, the Valves # 7 (intake) and # 9 (exhaust) I cannot get any space or play in there to make the adjustment, the push rods and the valve springs just keep going up up up when I loosen the lock nut and valve adjust screw. Is there some other technique I should be using?
Also, want to confirm this chart below is correct for 1962, 235ci Truck Engine:
Valves (from front of engine (water pump) going back to cab
1 - Exhaust
2 - Intake
3 - Intake
4 - Exhaust
5 - Exhaust
6 - Intake
7 - Intake
8 - Exhaust
9 - Exhaust
10 -Intake
11 - Intake
12 - Exhaust
Sincere thanks. Specifically, how to do adjustment on Valves 7 and 9 is needed, cannot get any play in them when #1 Cylinder is TDC.
