One ported head vs another...
What is the difference between lets say a patriot head and an AFR head as far as porting goes? There both ported, so what makes the more expensive head so much better?

AFR uses their own castings. Patriot ports stock lsx heads. Patriot can't touch the new AFR castings.

So i guess if you have a FI or max effort N/A car, it is better to go with the top of the line head. But what about if you want max power on spray? Will the better head make that much of a difference?

For any power adder the AFR heads will hold up better and produce more hp.

If you can afford an extra grand for AFR just to gain bragging rights on top flow number when you're at peak rpm go for it. Otherwise it's a waste of money over the patriots. http://edigras.iweb.bsu.edu/headscam.htm

The AFR's will have thicker sections over a ported stock GM casting, so if you are spraying or FI that would be more reason for an aftermarket casting such as AFR, DART, etc. The heads are structurally more robust when finished. Patriot does nice heads though and a lot of guys make good power and are happy with them. But for spray or FI, aftermarket castings would be stronger.
