Here is part of an email I wrote I thought was wort pasting here.

... The following I found in a forum.
____________________________________________________________________________________________________________

Just got off the phone with TEA , they gave me some flow numbers using a 4.500 bore and a 5 angle valve job he said trickflow ports there own heads not tea. do you guys think these heads can flow these numbers? also listed tfs numbers and tea small bore tea 4.500 bore tea 4.380 bore trickflow 4.625 bore 3 angle valve job.100 80 / 66 ----------- 77.6 / 57.9---------- 81 / 58.200 161 / 127---------- 138.1 / 117-----------162 / 115.300 250 / 175---------- 211 / 158.2-------- 262 / 160.400 320 / 215---------- 287.9 / 199.3-------- 332 / 196.500 370 / 245---------- 343.3 / 236.7-------- 370 / 223.600 400 / 271---------- 369.5 / 259.9-------- 388 / 261.700 407 / 275---------- 386.8 / 275.8-------- 401 / 290 .800 414 / 280---------- 394.4 / 287.3-------- 408 / 302

Trick Flow and TEA are part of the same company.
​The guy at tea said he does some hand blending an a 5 angle valve job where as trickflow does not . this is just what he said . im just wondering if the head will flow those numbers on a 4.500 boreI had some ports on the proto type head right at 400 cfm. I think with the chamber work that Tooley did, the 408 number probably is correct.
___________________________________________
I had rather have the extra compression and forgo the extra flow, unless I was on the hose.TEA's bench is very Liberal. TFS's bench is a good number.I also had an exhaust port on that head go 281 cfm, we were just trying to find two good intake ports and one exhaust to digitize.I have been waiting to see someone buy a set of those heads and post some dyno numbers. I ran a 5.67 with those proto type heads in my 86 notch at 3100 lb.
________________________________________________________________

Now these are the P51 numbers (see side bar)
The P51s look better. 
Here is a magazine build http://www.popularhotrodding.com/tech/0906phr_big_block_ford_engine/#ixzz3FxAWjd00
It made 775Hp at 6500rpm with 532CID P51 heads 273/280 @ .050 109LSA solid roller.
They also tested a 260/268 cam drop peak Hp to 728, but keep in mind loss Hp with a cam is due to loosing RPM the torque changes very little.
Their first combo made 511Tq at 3900RPM and they claim 600Tq @ 3900 with the smaller cam.
Looking at my builds I made 664 @ 3900 with a 253/253 hydraulic cam which is more equal to a 260 solid.
The motor I built with a 236 cam made 666Tq at 3900 639 @ 3000 verse 647 for the 253 cam.
Keep in mind different dynos. 

What I've seen with these big blocks is they do need enough duration to feed the engine and that duel plenum manifold do help low RPM torque like you would expect. 

(Name) the build you are looking at claims 875HP
​ I made peak Tq @ 4600RPM with the 253 cam, if he is making it at 6200rpm (hard to believe) then peak Hp must be well over 7000rpm.
What torque does it make at 3000RPM?

The magazine build with the 273 solid cam made peak Tq at 5400rpm 
I use a 273 solid in a big Chev that made peak Hp at 5800rpm with a single carb, 6200rpm with a tunnel ram (860Hp)

 Kaase gets $18,700 for his motor with Scat crank and rods.
Figure a Callies crank cost $1000 more and Oliver rods another $1000. 
There are engine builders who have built way more BBFs than me and know what to expect.
I don't see anyone offering the Eliminator heads, probably because it would scare off most internet searches, and people who buy real race engine know who to phone from being at the drag strip.
I'm hoping someone will show up, maybe you and have me build using the new AFR heads, so I can be one of the first show publish results. 

I think the Eliminator heads are too much for the street unless you have tons of money.
A street engine lives most of its like with a relatively closed throttle.Even when you stump it, it is mostly first gear or often second to try and get traction and it climbs from 2000rpm to 6000, then shift and lift.
As such a lower Hp motor will blow off one with a monster racing cam in it, and giant heads.
A motor only pulls in as much air as it needs, and the number is not comparable to a flow bench, but say the engine pulls in 200CFM at 3000RPM and one head flows 400CFM and another 360CFM, do expect the bigger head to make any more power.
It is at high RPM size matters. 
That in part is why I'm hoping the AFR heads will increase power at 3000RPM over the P51. 

Compare, my BBC made 657Tq @ 3000RPM :- 587 = 1.11 and my BBF made 647 :- 557 = 1.16.
This proves superior CFM flow does not make more low RPM torque, but as they say you don't race dynos.
What that means is acceleration is control at a certain rate where a car isn't.
Typically a small port motor will accelerate through low RPM faster.One more point.
The BBC number was with the tunnel ram which add CCs to the intake tract.
With a single carb which reduces total port volume Tq at 3000 was 680 :- 587 = 1.15 which is a closer match to the BBF. 

Here is someones BBC build shown on the AFR website
Note that at 6100RPM the 598 with huge 385cc heads made 895Hp whereas my 587 made 856Hp with much smaller 335cc heads. 
Bottom line performance start with sound thinking.

You are on my newer website. I had intended it as a replacement, but I decide to keep my old one.

It is a little out of date, but still has useful info

Click Stroker Engine

Below are dyno print out of these engines.

The are three test, all made peak Hp at 5500. They were street motors.

To push the peak Hp RPM up would require more camshaft.

Here is a magazine article showing 775Hp @ 6500RPM

New era in BBF torque curve

   See Article Click Here

Here is an outline for two engine builds, lowest cost verse serious performance. 

The idea is to give you some idea of the costs.

Your big block build will be unique, the final cost will depend on the parts you want.
