the difference heads small block

I got J heads on my 340. They were 1.88, with a cut, some polish and what not they are now 2.02 and they flow excellently and run great, best of all J head's don't break the bank. There are some guys (even on here) convinced their X heads are worth 1g. Unless it's a "date/part correct" resto, they really aren't. The X head hype is just that, hype. A J or X head with a really good port job can still flow 250+ CFM and make you more than happy in a street car.
