AFR 205 Mongoose Heads?
So I have the opportunity to buy a set of AFR 205 Mongoose heads ported by Tony Mamo. Currently I'm cam only (torqued v2), bolt ons, ls6 intake, and a 78mm nitrous outlet plate. The price of the heads is $1500. I know that AFR makes excellent products however with all the new heads coming on the market at very fair prices I'm wondering if I should just take a pass on the AFRs. I have had my eye on the new AI ported RHS/Dart heads and the new PRC as cast 225s. What are everybody's thoughts? Also what questions should I be asking the seller regarding what Mamo did to the ports/valves/milling etc? Thank you everyone.

Tony doesn't port them, he un-shrouds the intake valve for the most part with a little bit of blending. So, because he opens the chamber (about 2 cc) you need to mill to get back the compression. Make sure to account for this when you size your cam. I went with a 0.040" Cometic and with the 224/228 I am running was below minimum on the intake side. Don't get me wrong, this setup performs but if you want a big cam and these heads are milled you may need to fly cut.
Tony's work is beautiful by the way so there is no question on that. But I would ask what the setup was that these heads came from and ask what rockers he was running. If he was running stock rockers, then I would not buy them as I would bet money they have worn guides.
