What's the biggest size AFR heads that one could bolt to a "stock" 302?

Yeah, I've heard a lot of complaints saying that the AFR flow numbers are skewed. I found this article

And it seems that the TF heads beat the AFR's in intake but lose to them in exhaust. I have not been able to find any other direct comparisons on near stock engines... though I am still leaning torwards the AFR's due to the fact that they pre-port their heads and that would be one less thing that I would have to worry about.

For the moment.... I picked up that set of 351C heads for $100 last night! They need some serious wirebrushing cause they look like they have been sitting for quite a while. The intake ports are clean but the exhaust ports have flaky rust inside that seriously needs removal and there is carbon caked penny-thick in the combustion chambers. Other than that, there are no serious show-stoppers. I'm gonna get medival on these things while I contemplate the AFR's to come this winter.
