I had a similar problem in my mod once with a engine it would only turn about 6,000 rpm and then start popping. Turned out to be weak valve springs something you may want to check.

check the wires to the module from the pick up coil sometimes they get pinched and cause this problem also check where the 3 wires from the module to the coil they some times break about 1/2 in two will still run but will miss at high rpm. make sure your primary wire is at least 14 gauge, a hei has a very high instantanios amp draw.

What size of air filter are you running and what is the power in your carb I ran into the same thing once I had too small air filter and wrong power valve small things can play an huge part in performance
