Hard to believe that people aren't freaking out about this: Rumors, LS blocks?????? 
I guess people are happy w/ their stock blocks? 
Hmmm.... oh well, carry on then.

Bottom line here is that we advertise accurately and guarantee our flow numbers to be plus or minus 2.5% which covers most issues in a production environment. If the owner of those heads would have contacted AFR we would have either improved his current heads or replaced them at no cost assuming we validated (on our equipment) that the flow numbers were indeed soft. I urge all of you to contact me personally if you're ever in such a position.
Let's keep this thread on topic and find out more about the Dart headed combination which looks very promising...
Thanks,

Even though it can't compete with AFR I think this head is a good alternative to the lowend budget heads for just a little extra.
Someone's misinformed.
Here's Patrick G's setup:
472 rwhp/420 rwtq SAE
M6, AFR 205s, TR 233/235 .644/.598 112LSA TRak cam, Mamo ported FAST 90mm intake, NW 90mm TB, EFI Live MAF-less tuning, Kooks 1 3/4" headers w/catted y-pipe, Spec 3 clutch, Ram FW, SLP Dual/Dual catback
With the extra drivetrain loss due to an IRS setup and an engine that has 78000 miles on it along with using a stock MAF and no speed-density tune, I'd say that they are a big competitor.

THIS setup? You're going to have to check yourself, bud. This setup was a "low-dollar" setup through a Borla Exhaust, STOCK MAF, full belts, STOCK rockers, 30# injectors, STOCK fuel pump, all through a Vette drivetrain, which eats quite a few more % than a solid-axle. This setup would easily make 500rwhp in your car with your additional mods in your "race setup": EFI-Live SD tuning, A short accessory belt, Electric water pump, open exhaust, not to mention the mega-aggessive LSK lobes you're using on that cam. I DO believe you made 455 rwhp without the EFI live tuning, full belts, and no electric waterpump on your "street" setup.
If ANYTHING, I should be honored to be compared with YOUR AFR setup.
Give credit where credit is due. Don't be pissed at Dart for producing an awesome head! Maybe you can fool the AFR crowd into thinking your car wasn't an ALL-OUT build, but you can't fool me
EFI LIVE? Give me a break Cheers.

Great number from everyone LOL! But this is about the Dart heads and Kraest setup not a pissing match between two head venders. Just give the guy a little credit for a car that made good numbers and lets move on with out the comparison. Two cars same everything to the last detail will dyno differently and that is just the facts.
