I love my Chevy Chevette!

New guy here and not an experienced engine guy. I’m rebuilding a ‘66 L72 427 original engine. Wanting to go with AFR or Trick or ??? heads. Understand I can run higher CR with today’s 91 octane and get some power. I’m not a racer just street guy that gets on it for a thrill. I’m also planning on a roller cam from the solids. I don’t have any sense of why AFR vs Trick. I don’t need to buy the cheapest just need advice from experienced Chevy guys. It could be they are about equal. I have no idea. Thanks in advance.
