You probably don't need an entire set. On the SOHC KA each lifter is part of a Rocker Arm/ Hydraulic Lifter assembly. They're self-adjusting. You can find them in parts stores for around $25 each. They probably won't have them in stock but will be able to order them. That's not a bad price for such an essential part of your valvetrain IF you can narrow it down to which one you need. This can be done using an automotive stethoscope ($10) or if you're cheap and experienced, a long screwdriver. Hold one end against your valvecover and the other against your ear (with your fist around it, I'm not trying to encourage ramming a screwdriver in your ear) and by moving it over each cylinder on both sides of the engine you can narrow it down to the noisy valve.
Remember you have 12 valves total, 2 intake and 1 exhaust for each cylinder. Intake valves are on the passenger side of the engine, exhaust on the driver side. See attached photo, it's exactly what you'll see once you've removed the valve cover.
There are 4 part numbers total for the different valve locations. One number is for the front of each pair of intake valves, one for the rear intake valves, one for exhaust cylinders 1 & 3, and one for exhaust cylinders 2 & 4.
Anyway, hope that helps. If you were already aware of all that and just needed a source for cheap lifters, sorry for the length.
