Pretty good read ! Thanks

Been waiting to see more about these.
With the revised valve locations sounds like existing stud girdles will not work & have to cut pistons as well. Wonder if an "A" type intake could be made to work with these to fit the rectangle ports?

No on the A460 intake the ports are way to low on the heads

What intake will they except ?

I am a big fan of the AFR Sbf heads . I just hope the BBF heads are as good or better than the SBF stuff.

Any stock style BBF intake will physically bolt up to them, as the intake flange is based on the factory CJ head, but the port itself is a "roval" which will benefit from the intake being port matched.  The Victor would probably be an easy match, and I'm guessing the Torker II will work better than expected....and really any small port intake will be an easy port-match.  Notice in the picture how the AFR port fits within the confines of the CJ gasket.  Rumor has it that the AFR single plane intake will be even taller than the Victor.  I expect they're going to surprise a lot of people.

Thanks for the pic and info ^^^^!

Not that impressed w the sbf heads myself

Which ones are you impressed with for the sbf ? just curious as the only ones I've messed with yet are the world Windsor sr. iron heads and the kaase canted valve aluminum heads both unported.

A friend of mine runs the high ports on his SBF 408,they work well for him.

How long is the rumor on the manifold runners Carl ?

I have run the 185 and 205 heads on four different engine combos and both heads have served me well.

 One thing I have learned is that the cam profiles are different when running the AFR heads versus the other heads of same size or compatibility .

Now that I have read about the BBF AFR Heads. They may be more trouble than they are worth.

We will stay tuned and hope for the best for AFR !

If you could get "near race head performance" out of stock size heads, that would be very attractive to those that don't have tube frame cars.

P-51 ?

yes exactly, more options is usually a good situation rather than "less " options

That's getting it done ! Congrats

the castings are ok, its all the valvetrain they come with thats crap. if they offered a bare casting it would have been better as we always put our own stuff in um.
