you don't have to us the l92 heads. u could go with the fast setup and afr. the l92 setup would be better for your 408. we have cnc ported l92 heads on special just give me a call

You can use either head but if you go with the L92s you will not be able to use your fast 90/90, you will have to use the L76 intake. So I Would use the AFRs and your fast intake.

You can do either. I stuck with cathedral style heads on my 408. I'm very happy with the results. I haven't seen enough stellar horsepower #'s on the L 92's to back up their flow numbers. If you allready got a fast you might as well stick the the LSx style heads
