have you guys used thease heads on any of your projects? How do they compare to afr heads or something like a texas speed cnc head?

This is an excellent budget head that we have used on a few project vehicles and have seen good power gains. In comparison to a patriot or texas speed cnc head, you can expect better gains from the Edelbrock, however you will not see as high of numbers as you would with a AFR or Trickflow head.
