Re: AFR heads down the tubes? (MC TORCH RED)
why are you saying "damn", and that they were the ones you were waiting on?
that first post on ls1tech was completely inaccurate, and Tony from AFR responded, about the third post on that thread. maybe you didn't bother reading down that far?
there are no "problems" with the heads, and they are not down the tubes. you guys are unreal.

The projected flow numbers aren't even near a good set of ported LS6 heads. What the hell is the big deal anyway?

Re: AFR heads down the tubes? (SpinMonster)
just curious which LS6 heads you're speaking of. stage II or stage III ? price? port volume? cross section area? there are a ton of reasons why the AFR castings should be top notch, and why people want them. I'm not going to rehash what's been said on this board and many others. But I'm curious to know what heads already out there might be comparable to them.

:iagree:
I keep reading how the ports are smaller and flow better. I am still very skeptical about top end power on this type of head. I'm sure the high velocity flow will offer good low end punch, but what about the massive top end power we all want. Right now, the LS6 head has nothing to prove.
They have their hands full trying to outperform a modified LS6 head. What I would like to see is Edelbrock and TFS design a set. The TFS heads were always superior in my opinion to the AFR w/respect to power and the Edelbrocks had better quality than both.

Re: AFR heads down the tubes? (marco383)
Over the past sevel months Richard Holdener (in Muscle Mustangs and Fast Fords Magazine) has run the most detailed aftermarket head comparison I've ever seen. All the popular heads and dyno testing. These were done on Ford engines, but the results would be applicable in principle to Chev engines.
I'm not siding with any particular head manufacturer, but just suggesting that many general truisms about different heads were brought out that confirmed a lot of my thinking over the years.
As I remember they tested 205 and 225 flow heads by AFR and of course many other manufacturers heads (and AFR's) of all different sizes (flow rates).
I considered the testing unbiased and the enormous amount of data that he created is a real education in head technology-not just top end performance, but all thoughtout the range and is something we all should read.
It certainly opened my eyes!
Hope you check it out,
Roy

Ive seen this happen with various products where the release date is pushed back numerous times.I think a lot of companies use this as a ploy to keep people out of the market until their product is finally released.

They are not going to be any better than the LS6 head, and who knows maybe some new head on the SB2 will come out we can all use. I don't see why everyone has a hardon for these things...

To all the "naysayers" and disbelievers...
WRONG.....WRONG..... and WRONG
To the people that have had at the least an open mind to wait and learn about a new product that on paper seems to have a temendous amount of potential from a company known to deliver....You my friends will be rewarded for your patience and curiosity....
I have been involved with dyno testing all week and will be posting some preliminary results this weekend....I wont have a minute sooner to do so (I just got home now from some of the testing and will be leaving 6:30 in the morning tomorrow to conduct additional tests)
AFR is very pleased with the results we are seeing and I will get everyone up to speed some time this weekend when the smoke from the dyno cell clears and we have concluded this first round of testing.
Will catch up with everyone then...

Re: AFR heads down the tubes? (Tony M)
When you get up to speed, make sure and post how much more power your heads make than the ported LS6's available. That is what I'm interested in. I have seen heads with high flow #'s that were worthless.
