It is up to the racer and/or engine builder to make sure that the runner volume and combustion chamber CC's are no larger or smaller in volume than what their particular engine corrected horsepower is approved by the NHRA Race Committee. The runner and chamber volume CC's listed below are what they are supplied from Edelbrock, not that they are approved for this volume in your particular class.

For example: Chrysler 383-440 B/B V8 # 60917 intake runner volume measures 210cc delivered from Edelbrock, the accepted intake runner volume that is approved by NHRA needs to measure 203cc's.

The aluminum head must meet the same specs as the cast iron....3/8 guides....chamber volume and port volume....so they are not a simple bolt on...
