WantaGT the crossover is an emmissions thing. You definitely want a post-header exhaust crossover, like a H or X pipe, but they have nothing to do with the head.
D.Hearne said:You can quote me all the articles you want, I got the flow #'s straight off AFR's site. Same as the Canfield #'s. So tell me why AFR would "low ball" their flow #'s? I'd still match my Canfields anyday against AFR's. Max flow isn't always what makes an engine perform. And larger intake valves like 2.02's against 1.94's isn't always a good thing. You end up having the cylinder walls and the chamber walls shroud the valve
No, could be it's because they buy more advertising space in the mags? Seems the two go hand in hand. You hardly ever see ads for Canfields ( come to think of it, I can't recall ever seeing an ad) But AFR's are plastered all over the place. Seems they're as popular as Chevy's87gn2 said:Why is it that every article shows the AFRs beating the Canfields? Perhaps because they're better?

Hell, even I can't recall, this thread's gone on so long now My Canfields are probably closer to the 165's with the 1.94 intakes. The flow charts posted show the 2.02 heads. Either way they stack up to the AFR's anyway you put it.Route666 said:Those numbers are basically the same in the article. I'm sure 5 HP / TQ / CFM could come down to random variations. Those numbers are close enough to be equal. Wasn't D.Hearne originally comparing them to 165s not 185s? ?

Route666 said:Now 25 is something. 26 less torque for the AFRs is also something. The average shows 9 HP and TQ over the Canfields, not exactly worlds apart.
