AFR heads

Just got off the phone with a tech guy at AFR and he was saying within the next year that they should be releasing a A460 style head. That will be nice to have some more choices, I would expect it to be just as good or better than the TFS A460 cnc heads.

Competetion is always good for the end users like us, but AFR has never really impressed me with their stuff.

EX:
Their 185cc heads on a SBF fall short in almost every aspect to the less expensive TFS heads.

A TFS 170fac head is better (in some areas of lift) than their CNC 185 head.
AND,...it's tested on a 4.030 bore and the AFR head is flowed on a 4.060 bore.

AND,.......when you start comparing the AFR 185 head to a TFS 185 head, they get blown out of the water

yeah thats why I posted, I have afr 225s on my car its been a 5.50 @ 127 on a 250. the trickflow stuff is really nice and there flow numbers do always seem to be higher but at the track the performance doesent seem to be any better, once I get my suspension worked out and put some more spray on it, itll go 30s im sure.

How old is the TFS A460 design now?, not sure. But if they are a few years old, perhaps a newer design from AFR may make some improvements? It will be interesting to see.

Im sure that Charlie can give a good history of the Trick Flow head evolution, but the current castings have been changed within the last 3 years to accomodate the 18-bolt option (BBF-3X). Without going to a completely revised design, like the Blue Thunder Thor...it will be pretty tough for anyone to economically compete with the Trick Flow A460 casting in its current state. You can buy them From Trick Flow all CNCed that flow in the mid 460 CFM range...pretty good. Guys like Phillip and Charlie can get quite a bit more out of them too.
With extensive porting, the current Trick Flow casting is capable of flowing in the 530++ CFM range which gets it in the C460 and Profiler neighborhood.
I have also read about the IDT "A" heads that also sound interesting.
Competition is good, but the guys developing the heads will have to look at the market, and see if they can get a payback on the $$ to develop the parts. Lots of good choices out there already....
Just my thoughts.

we have a set of the 205 AFR's on our 306, the castings are ok but all the hardware was junk. You can't or at least when he bought them could you just get bare castings.

i did change valve springs and retainers as well as using shaft rockers. the motor puts out over 7oo hp

my AFR185 headed 347 has put more than one big block chevy in 2nd place, one of the 5.0 mags did dyno test on heads some time ago and although the afr's did not "flow" as much as all heads tested they did produce more horsepower and torque. Rememer flow numbers do not always tell the whole story.

AFR is sharp and proud of their products too. I've owned some and loved them.
Any guesses on about what their A-Style would cost? I'm guessing 3,500 half cnc'd.

it be nice to have another choice on the market.

X2,TFS does make a good head for our big fords but I realy doubt AFR would invest the money in R&D and tooling, just to put out a head that was sub-standard to whats already available.

Bump !

Any more info on these heads ? I would like to try a set on my 466 as I have had good luck with their sbf heads. Thanks

They are a CJ head, not an A head. The two links below are the latest and greatest.

Thanks for the info! 
I guess no one has any real run time on an engine with them yet ?

I spoke with "Joe" at AFR today, he said they were going to try and release a 270cc and 305cc version by April 2014.

anyone know if Ken still owns/works at afr?
