Are stock over-the-counter replacement heads allowed? Asking if the replacement 370 heads can be used in place of the 186 heads on a small block chevy. Thanks, John

You have to find a peice that fits your build and the criteria outlined in the rules and bring it up for approval! If it looks stock or you have a good case we will review it! This goes for all marques!

World block 84030 is a 400 sbc and is NHRA approved as a replacement.
