Yup, I talked to an AFR rep at SEMA and he said they're planning on three new heads with different intake volumes and different amounts of port relocation on the exhaust. He said they're largely focused on increased performance with minimal increases in port volume (high velocity). Should be interesting to see what actually hits the market.

Did he mention what all custom stuff will be require to run them? Pistons, stud girdles, etc...

Agreed should be interesting! Nice to see at least they are taking an interest. Steve

There wasn't any discussion of valve relocation. We did talk quite a bit about exhaust port location though.

another set of small valve heads which may be good for the street cars but with valve relocation you don't have the luxuary of a "bolt-on" upgraded head without changing pistons or modify pistons if possible, and for the performance increase they claim its not different than the P-51's. to build a complete new motor around these heads i'm not sure that it will be any different than what is already available, performance wise. i would bet that dollar for dollar a good set of TFS streets would flow just as good with less work and you don't have to change pistons or buy different valve train. but on the other side of the coin another set of heads for the BBF is great addition and gives every builder an option he did not have before.

Another cylinder head option is always welcome imo. With regard to efficacy and ease of use... Time will tell.

If I didn't know better I would swear I was looking at a CHI cleveland casting...

AFR desperate

AFR is very late to the party and is just trying to jump on the bandwagon. In my opinion they are not welcome. To make a street head is a good indicator of this. To me they are just a US copy of Pro Comp. and are trying to make a buck in the BBF world. Their Chevy business must be dead.

I've always had very good results anytime I've used AFR... I bet their big Ford head will be very good if used for the intended purpose, whatever that might be.

AFR

Not sure what Vandy dudes problem is but I welcome AFR into the BBF world. They produce very nice cylinder heads.

What "Vandy dude" is saying, DGS, is that there are plenty of street wedge heads on the market and he wants to see more serious racing heads for the Ford--there aren't enough racing wedge heads out there to suit his specific needs. C heads, Thor heads, etc don't quite cut it when compared to the non-Ford competition, they're just not going to be able to support 5000+ horsepower.

I don't want to burst your bubble Paul but if you want 5000+ HP you and Vandy better build it yourself, and I'm sure you will.

DGS, your response looks sarcastic to me. I'm only explaining where Van is coming from in regards to his response to this cylinder head, as you didn't understand.

In regards to building enignes that generate thousands of horsepower: that's nothing new over in this camp, it's been going on for decades and with several makes. But multiple thousands with a Ford wedge head is extremely difficult indeed. Hence, why more BBF race heads are being desired (Van prefers wedge over hemi).

Paul, your response didn't make much sense. Why would AFR make a cylinder head good for 3000+ HP? How many customers would they have? If you and Vandy would have us believe that all other companies are out there to develop cylinder heads only for the end user and profit be damned, you better get your head out of the sand.

How is this response
It's going to be a second rate street head, just like there small block stuff. If they spent the time and $ to build a good head to compete with the TFS A heads which is great stuff, but older technology, Then think about building a street head based on there reputation that was earned. Thank you TFS for still making great Ford heads for a great price.
Airflow will treat the Ford as second rate, not as an equal to their Chevy line of products. You can belly up to the counter and buy it but I'm going to pass.

Well we will have to wait and see how well they have done their homework on these then.

Given the AFR headed SBF's loss's (and not by significant points) to the CHI headed clevors / clevelands which ruled in EMC's past, the assertion that they offer a second rate head is imo incorrect and unfair.

I would be interested to see what the BBF offerings are all about and what if any improvements they can offer over the P-51's which with a 265+ cfm exhaust port will support 1000 hp with a 2.300" intake and port work. That might be hard to match... ( yes I am aware of the intake used in that combo)

In addition the SCJ-A's with bowl work make wicked street heads any way you try to slice it.

I will take a wait and see attitude here...
