You may have a great set of heads but to utilize their full air flow potential you need more cam, more compression and a lot more RPM

Rounded off and all things considered we would use a Q-750 Mechanical to give you decent drive-ability on the street. This is assuming you have the correct convertor or a 4 speed and a good rear gear ratio.

22/36 Ignition timing? Are you using one of our 14* bushings in the MSD distributor?

You will need to consult with a Quick-Fuel expert and get the Idle Air Bleeds adjusted at the factory or at least supplied. The generic air bleeds are not matched to your cam and compression.
