My thoughts are a broken cam but you said you adjusted the valves. You would have noticed there was no lift on those rear cylinders when you were making adjustments. Therefore I would suspect something in that ignition circuit. Maybe swap some plug wires or plugs to see if the problem moves with them. Possibly the distributor cap was not on straight?
If your plugs and wires all check out good can you do a quick compression test on the cylinders? it will tell you of there is possibly a mechanical issue. I would tend to think it's something mechanical because fuel and air would get to all cylinders if it gets to four of them. Spark should also get to all cylinders, if it gets to four of them, if the distributor shaft / bearings are good. I would do a compression test and possibly a leak down test.
