You need to ask yourself if you are looking to keep stock appearance. Hei would be most efficient and reliable. A GM Hei or even a summit brand would be just fine. I am assuming you are not looking for horsepower. Keep in mind those points did work just fine for the last 40 years. If you go HEI you need to be sure you have 12 volts at the distributor. Many point systems lowered ignition voltage. If you are looking for power the best system you can afford would be best.
