HEI is the easiest to maintain and it's an easy swap IMO. Good choice. If you need any wiring tips just ask..... The HEI will always outperform a stock points distributor due to the added volts it can handle. You will get a stronger spark. I have one with the stock module and another with the HiPo computer chip style module. I can't tell a big difference between the too.. I like to add the Super Coil on top of the cap.
