I have had a lot of different opinions though, a lot seem to think AFR is the way to go though

You might want to take a look at this thread....

Very informative and shows a very large cross section of heads from all over the country. The beauty is that all the info is taken from the same testing equipment. Look how efficient even the 205's are in most company that have 30-40 cc's of additional volume advantage....thats beyond huge. The numbers speak for themselves. Call me at AFR if you get a chance....Would love to speak with you about your project goals....I'm confident the AFR's will deliver and would like the opportunity to discuss their design benefits with you.
