Coach forget about thehei!!1 It is intended for fuel injected engines that run a lot leaner than your carbed one will run.. There is NO BENEFIT from running hei on a carbed engine...NONE! Save your money and spend it at Hooters or somewhere you will see some benefit.
The exception to this rule would be if you plan on running your engine at 6,000 rpm or higher.. if so your present spark setup will not work at those rpm..
