AFR / LS6 Heads ?
The main purpose of my post was to highlight how weak yours was and let people know that just buying a few of the same components in a particular package doesn't guarantee the same results as the whole package or even close....an issue that comes up time and time again.
Why have you been so argumentative and generally negatively biased this entire thread??

Exactly. Joe Sherman stated on another board that he has sold the exact same components he uses to build a motor to people and they will come up 40 to 50hp short of what he gets. Proper assembly of the componets is a big part of getting all the horsepower you can. Tony alluded to degreeing the cam as part of it.

Tony,
I just ordered a set of 205s. You probably have a request there to mill a set to 64cc from SDPC. Anyway, how much am I leaving on the table at 64cc vs 62cc? I am going to install a 228/232 cam similar to LGs G5X1 cam on a 112 LSA with 2 degrees advance and a .045 gasket.

Many of the board sponsors, including Tony @ AFR, offer a good quality product. What you do with it once it arrives is entirely up to you. "X" head with "Y" cam and "Z" headers may work well for me, but perform dismal for you. The difference is in the details, like degreeing the cam, checking the valve clearance, milling the heads to get the compression correct, fabbing a custom Y or duals behind the headers - all the stuff that people forget when they say "I can do that myself, I'm not paying $$$$ for you to do that".
Another twist in the "speed costs money, how fast do you want to go" and "cheap, fast, reliable - pick only two" vein.
and please don't take my reply to your post personal. I'm responding to you as well as the masses who have all posted similar questions to yours in the past.

I have the AFR 205’s and 224/228 581-588 114+1 cam.
The rest of the setup is unremarkable. Stock TB, stock LS6 intake, old TPIS headers, cats, MN6, 410 gears.
I put down 440 RWHP and 417 RWTQ on a Mustang dyno. It runs 124 mph in the ¼ mile pedaling and granny shifting.
I have no association with AFR and have never even spoken to Tony.
The results you witnessed are far from the norm. I’m not sure what your agenda is.

Verdad Gallardo If you haven't already, you should review the Interesting Flow Data thread, as should anyone who finds themselves in the market for cylinder heads. Big numbers on a flow bench can mean big money for a product, and there are enough people out there that you'll find some whose claims are bogus. It is hard to establish a level playing field and get a true apples to apples comparison.
Once you see who produced the results in that thread, you might question the manner in which they were derived, and how accurately they portray the products tested. You should note that no names were intentionally given by the presenter, and the all numbers (some better, many worse) are displayed for all to see. You may see the trend that develops leaves a little doubt as to whether or not you always get what you pay for.
