To adjust valves it is not important to be exactly at TDC, only that the lifter is on the base circle of the cam. Use the EO/IC method.
Starting with cylinder No. 1 with the valve cover off, rotate the engine until the exhaust lifter begins to move upward. This is the point at which the exhaust valve is opening (EO), meaning the piston is through with the power stroke, and its about to begin the exhaust stroke. At this point, the intake valve is closed and the lifter is on the base circle of the camshaft and can be adjusted.
To adjust the exhaust lash, turn the engine over until the exhaust valve has completed its lift cycle and the intake valve begins to close (IC). Now, the exhaust lifter is on the base circle because the piston is finishing the intake stroke and about to begin compression. Set the lash on the exhaust valve and youre done.
This needs to be done for each cylinder.
Can use the starter to bump the motor to the desired position since the exact position is not needed.
